help! i'm using this code but instead of giving me the raw rgb values i get numbers far into the thousands and green and blue are always the highest even if i show red. plus they are almost always the same.
with kind regards jelle, (first year university student robotics)

Yes I'm got same kind of problem

i don't want raw values what should i do now ?

This code should give you big numbers. Adding the following code will print the colors that are being detected.

if green<7000 and blue<7000 and red>12000: print("red") temp=1 elif red<12000 and blue<12000 and green>12000: print("green") temp=1 elif green<7000 and red<7000 and blue>12000: print("blue") temp=1 elif red>10000 and green>10000 and blue>10000 and temp==1: print("place the object.....") temp=0
