I need a dark green grass color and so far my green looks like the school green color!!!! All I have is Wilton colors to work with. Do I just keep adding more green leaf color or do I add some black or brown?
I usually add black, it doesn't take much. HTH
A dark color of any kind needs time to 'develope' the color -- make it the night before you need it.
The more paste color you add the longer it needs to 'develope'. It also will darken a bit once it is exposed to air.
You could use a little black, but I think it turns my green more of a gray/green shade. I mix moss green and kelly green to get a darker green color. HTH
