While editing the wiki, I stumbled across this guide adapted from ~sciocont’s advice on how to accurately design and colour cells and organelles. Might be useful for modellers to think about.
Rules of thumb for asset design:
Psuedo-randomness. Textures with organic order, e.g. Perlin Noise, Voronoi Textures (useful for GUI) and real-world organism texturing.
Uniform sharpness. Texture should contain sharp/bold, medium sharpness or soft edges only. Try sharp edges first and blur to desired degree. Individual objects always have uniform focus, objects blurred depending on distance from camera like microscopic image.
Light, desaturated colors. Matches real microbe pigmentation, i.e. mostly transparent.
Realistic color types. Avoid purples, pinks or yellows (not found in nature). Focus on blues, greens, reds and pale oranges like this color palette (accented in white). Exceptions can be made where distinction is needed, e.g. a purple nucleus.
