VanessaE's Unified Dyes ======================= The purpose of this mod originally was to supply a complete set of colors for Minetest mod authors to use in their recipes. Since the default dyes mod that is supplied with Minetest "common" is now usable (via flowers, also included in "common"), this mod has become more of an extension pack. Unified Dyes expands the standard dye set from 15 to 90 colors. IMPORTANT: This mod is not intended to suggest that you should use the entire palette. Rather, I was hoping people would just choose maybe the dozen or so most useful colors to use in their mods. Dependencies: default and dye from Minetest "common". This mod will NOT work without these. This mod will NOT work without these. The default dye mod is normally activated only in the standard "build" and "minetest_game" games, or perhaps if someone has a modpack or game that includes them. Recommends: flowers from common. License: GPL 2.0 or higher for the code, CC-by-SA 3.0 for the textures. Install: Unzip the distribution file, rename the resultant VanessaE-unifieddyes-blahblah folder to just "unifieddyes", and move it into Minetest's mods folder. The Palette: [ http://digitalaudioconcepts.com/vanessa/hobbies/minetest/screenshots/color-swatches.png ] [ The official palette, showing 84 colors and 5 greys. ] In the image above, the "50%" markings on the left next to each shade mean 50% saturation for all hues in that shade line. Note that the "light" shades don't have (or need) that variant. For the greys, the percentages shown are of brightness relative to pure white. There are three special cases: Light red has been aliased to default pink dye, and dark green has been aliased to default dark greey dye. Brown dye also exists in the default set, it's just not shown in the palette above. Usage instructions, technical information ========================================= Getting Started --------------- First thing's first: you're going to need to harvest some materials to make the dyes from. For this, you need one or more of the following: roses (red), tulips (orange), yellow dandelions (yellow), cactus (green), geraniums (blue), violas (purple), coal (black), or white dandelions (white). Simply wander around your world and collect whichever of the above you need to get your colors. [ http://digitalaudioconcepts.com/vanessa/hobbies/minetest/screenshots/unifieddyes1.png ] [ The 8 base colors directly obtainable from a material in the world. ] Simply place one of the above materials into the crafting grid to obtain four portions of dye in that color From those initial 8 colors, you can directly fashion another 11, for a total of 19 standard colors (including the various greys): [ http://digitalaudioconcepts.com/vanessa/hobbies/minetest/screenshots/unifieddyes2.png ] [ The complete 19-color standard set. ] The standardized colors and their crafting methods are as follows: * Red (0°): one rose * Orange (30°): one tulip, or put one red dye and one yellow dye into the crafting grid to mix them (yields 2) * Yellow (60°): one yellow dandelion * Lime (90°): mix yellow + green (yields 2) * Green (120°): one cactus, or mix yellow + blue (yields 2) * Aqua (150°): mix green + cyan (yields 2) * Cyan (180°): mix green + blue (yields 2) * Sky blue (210°): mix cyan + blue (yields 2) * Blue (240°): one geranium * Violet (270°): one viola, or mix blue + magenta (yields 2). * Magenta (300°): mix blue + red (yields 2) * Red-violet (330°): mix magenta + red (yields 2) * Black (7.5%): one piece of coal * Dark grey (25%): mix one white + two black (yields 3) * Medium grey (50%): mix one white and one black (yields 2) * Light grey (75%): Mix two white and one black (yields 3) * White (95%): one white dandelion. The degree figures are the colors' hues on a standard HSV color wheel, and are what I used in the textures supplied with this mod. For the greys, the figures in parenthesis indicate the intended brightness of the shade, relative to white. Note that black and white don't go all the way to the bottom/top of the scale, as doing so may crush some details in textures made in those shades (see below, regarding semi-automatic texture generation). Darker/Lighter colors --------------------- To obtain a dark (33%) version of a given color, use two portions of black dye along with the base color from the list above, which yields three portions of the final color. To obtain a medium-brightness (66%) version of a given color, mix one portion the base color with one portion of black dye (for example, medium lime = lime + black). All such mixtures yield two portions of the final color. To obtain a light (150% over full) version of a given color, mix one portion of the base color with one portion of white dye. Yields 2 portions of the final color. Low-saturation colors --------------------- To get the low saturation (50%) version of one of the base colors, mix one or more of white, black, or a shade of grey with the desired base color: Dark, low saturation: dark grey dye + color (yields 2), or two blacks + 1 white + color (yields 4). For example, dark, low-saturation red = red + dark grey, or red + two black + one white. Medium brightness, low saturation: medium grey dye + color (yields 2), or black + white + color (yields 3). For example, medium, low-saturation green = green + medium grey, or green + black + white. Full, low saturation: light grey dye + color (yields 2), or 1 black + 2 whites + color (yields 4). For example, bright, low-saturation blue = blue + light grey, or blue + black + 2 white. There is no low-saturation version of the "light" colors. Red + white always returns default pink dye, and black + green always returns default dark green dye. RGB values ---------- All RGB values and filenames for all colors and shades of grey are represented in the file "colors.txt" (which was generated with the bash script "listcolors.sh"), included in the distribution directory. Note that listcolors.sh is an example only and was written for a different set of textures than what Unified Dyes includes now. Misc. Notes ----------- If you need to use /give commands, the item names for the standard set of 12 regular "full" colors (plus pink, brown, and dark green) is simply "dye:color", e.g. "dye:red", "dye:pink", or "dye:skyblue". Greys have a similar naming convention: dye:white, dye:light_grey, dye:grey, dye:dark_grey, or dye:black. For everything beyond those initial 19 colors, the item names are of the following format: unifieddyes:{"light_" or "medium_" or "dark_"}{color}{nothing or "_s50"}. For example, low saturation dark yellow is "unifieddyes:dark_yellow_s50", while light normal-saturation red-violet would be "unifieddyes:light_redviolet". See the texture filenames in the textures/ folder for further hints - all of the item names follow the same format as the corresponding filenames, save for having a colon (:) instead of the first underscore (_). Semi-automatic generation of textures ===================================== The texture generator script ---------------------------- Obviously, in order for this mod or the above template to be useful, you'll need textures. If you plan to support the entire range of colors offered by Unified Dyes, there is a BASH script included with this mod as well with the above template named gentextures.sh, which will, with an appropriately- colored and appropriately-named source texture, and possibly an overlay texture, generate a complete set of colored and greyscale textures. The script requires bc (the calculator program) to handle some basic math regarding the hue adjustments, and Imagemagick's "convert" program handles all of the actual conversions. First thing's first though - you need source textures. Using your favorite image editor, create a single version of your desired texture. Draw it in the brightest, deepest shade of RED you can muster without losing any detail, and save it out. Ideally, you will want the average color of the texture, when taking into account all bright and dark areas, to be as close as possible to the hex value #FF0000 (0 degrees, 100% saturation, pure red) without losing any appreciable #detail. Save this source texture out as a PNG image, with a filename of "whatever_base.png", where "whatever" is the one-word name of your mod - for example, mymod_base.png. If you want to add an image on top of the colored blocks, such as a frame, which you want to be the same color throughout all of the textures, create it now. It should consist only of those parts of the textures that you want to leave unchanged, with some level of alpha transparency everywhere else, depending on how much of the image needs to remain unchanged. Save it out as a PNG image, using any filename you want, for example myoverlay.png. Now, use chmod to make the script executable, if necessary, and run it. If you don't need the overlay, you just need to supply one command line argument: the base name of your mod. The script will use that parameter as the basis of its texture filenames. For example: ./gentextures.sh mymod The script will then look for mymod_base.png and copy and convert it into things like mymod_red.png, mymod_dark_blue.png, and so on. If you want to use an overlay also, skip the above step and run the script with the base name as the first parameter, and the complete filename of your overlay as the second instead. For example: ./gentextures.sh mymod myoverlay.png Otherwise, the program will iterate through all of the hues and shades that are supported by unifieddyes (though this is done manually, not by reading anything from the mod), compositing your overlay image in after the recolor step, if you're using that option. All of the output files will be placed in a new folder, generated-textures/ in the current directory. Note that the script looks for the above files in the current directory also. The script has a third mode as well: ./gentextures.sh -t mymod myoverlay.png In this mode, the script will leave the base texture mymod_base.png unchanged, and instead will rotate the colors of the overlay image and then composite that onto the base texture. The same color changes will happen with the overlay in this mode, so it's a good idea to make the overlay some fairly saturated shade of red. Along with that, the base image should be some neutral color; any color is fine as long as the result is what you wanted. The program attempts to verify that the files you've asked it to use will actually work, and will exit immediately if the any are invalid, missing, etc. Use your favorite image browser or file manager to review the results in generated-textures/, and if they're right, copy them over to the textures/ folder in your mod. Note that this script does not generate brown and pink variations of your base texture - you'll have to do those two manually.
