in understanding rgb led's

Well i guess i your rite, they should be "diffused" but the colors stilll don't mix. They are like...1,5 - 1.0 meters away from the wall. Is it worth trying to diffuse the alrady diffused leds?

what happens if you move them 5 cm from the wall? Does the distance from the wall have an effect on the mixing of the colors?Kevin Pierson

Well nothing realy, 3 circles on the wall become smaller :D But if i bring them close to the wall and hide them with a peace of plastic, turn off all lights maybe, but just maybe some of it appears to be yellow, or oragne or whatever "mixed" color I'm trying to get. Its a bit better when i move far away from the LED's. Maybe everything is ok and I'ts just me and the fact i expected more. I'll try to post a video or photos of the thing at work, that way It'll be easyer for you to see if I'ts just me or the LED's suck :) Thanks !
