Ok, so I completely neglected to find out DBH’s color limit when I made this. But I have some questions about them…
What is the definition of a halftone?
If I use the burn or dodge tool to shade does that make it a new color?
would gradients and noise count as a color?

No. This is too large to have so many colors. Please look at our printing 101 area in the submission section. It will answer many of your questions.
