Don't mean to be rude or the like but there aren't any rules really stating I HAVE to use certain colors are there? As the tileset I'm making will use very solid and bright colors similar to that grass.
Grass can not be painted by selecting 2-4 values of pure green and then randomly spraying until the distribution seems even. This is basically white noise, snowstorm, ant race, whatever you call it when the channel isn't coming in. It has no logic, no order, and thus conveys no information. I recommend starting over and painting some grass. You may as well start with the classic:http://www.petesqbsite.com/sections/tutorials/tuts/tsugumo/chapter1.htmRecognize #3? Grass has structure and logic and a wide variety of interesting colors and hues. Learn them and use them!
