Does anyone know how to implement avr to vga that support RGB colour ?
The code that i got in google only support for monochrome.

You certainly got the monochrome version here :

If you take a look at the following link,
http://www.elektronika.lt/schematic/theme/79/7090/, you will notice that you
can drive the 3 colours directly :

It said in datasheet we have to decouple the AREF pin with capacitor, but it
didn't said the value.
Does anyone know the value ?
0.1uF works.
Make sure
Just use common sense.
I like to think I have some level of common sense, but I try to know my
limits. I believe common sense comes with experience, and I have very
little in this area. I too had been guessing what capacitance to use to
decouple the AREF pin. I wish I could have common sense

Well, from my point of view there are solutions which just work and
there are the more engineered solutions.
A 100nF X7R ceramic should be okay.
1uF

I found that the 2.56V reference varied from ~2.3V to ~2.7V
across devices in the CAN64 parts I have been using.
The values still fell within what the table said where acceptable.
If you need repeatability from

calibration factor in EEPROM?
Labor costs of doing that when you are dealing
with lots of units, in this case hardware was
a cheaper system solution.
