and we have a winner!!!
We have 3 colors and 5 panels.
Step 1
Total combinations therefore are 3^5=243
Step 2
We now need to remove all the combinations where only 2 or less are used.
2^5=32 We have 3 combinations of paint Red/Blue Red Green Blue/Green
(2^5)*3=96
243-96=147
Step 3
We now have 147 however in step two we removed all red/blue/green combinations twice. i.e. once for Red/Blue and once for Red/Green which would remove RRRRR twice.
We add this 3 back to arrive at 150
Answer = 150
