Hi, my DMX 3 works off of fixture selection as it's main source of channel control, so you need to maybe make groups for quick and easy access to sets of channels. does that make sense?
Here is my overview on what's new in MyDMX 3: https://youtu.be/Fz8V8nOA3I8
List of colors, as in pre-mixed? You can stack cues in MyDMX 3, so you very well can make a whole group of just color combos and whole rig colors etc.
Watch this video it may help explain some of the options you have: https://youtu.be/AY5mw3AqCNI
