Driving string of RGB LEDs over distance

I did some experiments with Kingbright 5mm RGB-Leds. It is not a good idea to use drivers, because you need to adjust each LED to the same white colour with all segments on. First use 2x47R for the 2 blue chips for a total of

50mA from 5V. then the green needs around 12mA, use ~120R and finally the red needs less current, 9mA with ~330R. Adjust the resistors for each Led individually, but keep the 50mA for the blue, as they are the weakest. Best to do this with a duty cycle of 50%, to avoid overheating. compare the color in a breadboard. The resistors can be of the 100mW axial ones, use shrinktube to cover them and make different lengths for each connection to avoid shorts. No PCB needed, which will only break. AWG 24 is to small, use it only for the gn and red and take AWG20 for gnd and blue. Do not use higher current for the red or gn, since you will overheat the chip and get the blue too weak.
