Yes those colors are the ones that cause the problems 99% of the time.

Remember, contrary to what the cut and paster moderators post on here (just a couple)
Humidity plays a big roll as to how fast the solvents get out, so when the humidity is high, it is very important that the first coat gets extra flash time.

A good rule of thumb is at 70 degrees 50% humidity or more first coat should flash 39 minutes.

Also with the blues and greens they tend to not cover as well and obviously if you now have 5-8 coats of base to cover there is a lot of solvents still trapped.

Worse part is when you see these contraction and hazing problems, they can also lead to poor shone chip resistance and or even de-lamination of the base, if solvents trapped in first coat or de-lamination of clear if just cleared to soon.

Water-base is even more critical.
