Delightful! The solve path makes this feel like three distinct puzzles.

That was beautiful.
Took me a minute to understand that there are 8 small palindromes and not 4 long ones.

The coloring is really good. I colored the whole grid into a rainbow. When the sizes of the numbers represented by various colors are sorted by the unequal sign, there is nothing more refreshing than this when the whole puzzle is filled!
