Colour chaser and effect rate/size fader

Hi,

I am new to road hog4 and recently i just watched a video on effect programming on MA console (in order to copy some of his idea)

However, I can't figure out how to properly set colour chaser with this lighting fixture (Robe Pointe with colour film) I tried to do it using Effect on Colour wheel. but I can't get a clean and solid colour. quite often, I will have half red and half yellow.

2. Could I assign one fader that can control effect size both Quelist on Pan movement and circle movement?

Thanks for your help
