Hi... I have designed a method of sprite recoloring that is different then most other sprite recoloring methods. In many of the methods I had seen, the primary recoloring method was "pallette swaping" where n colors are used to draw the sprite, and there are n colors to remap those color to. Each specific color gets remapped to another specific color.

 In my new method, the majority of pixels retain their original color, there are only two 'configurable' colors (instead of the whole pallette) but these two colors apply shading and do not replace exact colors... 

Here is example:

The process is as follows:

 1) Create a new SpriteSheet with 8bits per channel + Alpha

 2) Create two greyscale images to define the "recolorable" area of each recolor layer (They don't actually need to be greyscaled, the tool will greyscale them if they aren't already).

 3) Combine the three files into a single file using a tool that I wrote .

 4a) Output sprite sheets with whatever color combinations required via tool I wrote using the output from the previous step as input.

  -or-

 4b) Use the output from step 3 directly in the project using a special shader.

I really don't think it is a terribly difficult work flow... you actually don't even need the tool, just create three images the same at the dimentions for overlaying.

This submission: https://opengameart.org/content/space-ships-0  (ships.png, shipsColorLayer1.png, shipsColorLayer2.png) was perfect.

I'm looking for anything really... I currently have only those ships... but eventually I want to have clothing and weapons and trees and flowers and walls and terrain, etc. 

I mean, Imagine having some LPC terrain in this format... you could have grass, rocks, cliffs... and you'd only need one instance of each 'texturing' then you'd be able to explore planets with Purple Grass and Green Acid water, or Orange Grass, blue sand and pink water...  instead of needing a different tile for DarkGrass-> rock and Light Grass->Rock, you could have simply Grass-> Rock.. 

Or for character customization... you could have the base layer customize the hair color and skin color while, then have a shirt of the same type of sprite... for a shirt you could even leave the base empty and have only the two recolor layers (shirt base color, shirt emblem color)..
