I agree, your plant looks pretty good, and the light yellow tint of new growth is perfectly normal, though it does appear to be pretty short yet for an Ice Cream.
Just how tall is it right now?
There are some tricks you can employ to increase chlorophyll production but once you start down the "Dr Frankenstein" path with exotic chemicals, you might get hooked & wind up with a 30 foot tall monster trying to eat your car.
You might consider planting some "water hungry" plants around the base to help suck up excess moisture.
A little extra potassium in it's diet never hurts, either, and phosphorus can deter some fungus growth.
