step by step

Answer 1

Answer:

mix them....

Step-by-step explanation:

Like if I say you have yellow,red and blue.

So first you colour the first object with red , then the next with yellow and the next with blue. You dont have any colours left with u so to colour the 4th object mix yellow and blue and it becomes green. After that to colour the 5th, you mix red and yellow that becomes orange. Then try to mix the colours with the same way but let me tell u before that limited colours can only be there.
