I just saw your tip about the reflections! I never knew about that and why some surfaces have that colored reflection, though that restriction did serve me as a nice challenge to work around with it (some CAS designs are inspired by the reflections themselves).
With this, however, I may now have more control if it actually gets in the way. Thank you!
You've been really helpful with your tips on patterns as well! Some I never think about but some I didn't know could be used in such ways.
