Re: 7-segment clock display
Generally the human eye is most sensitive to wavelengths of around 555 nanometers which is squarely in the green part of the spectrum. So although both displays have similar power output, the green will appear slightly brighter in most circumstances.

Re: 7-segment clock display
Not sure what you are attempting to do there. DP3 and DP4 are internally connected in the display module. They can't be controlled individually. The pair is controlled by pins 2 and 24 of the HT16K33 driver chip on the board.
