I'm new to color Nonograms, and this is the hardest one I've ever done. I have no idea how you can do it without hints or red Xs. Not saying it can't be done, just that it's above my skill level.

Tiny areas... a few close shades of all the same color... this wasn't a fun challenge, it was just irritating.

Super easy to guess the outline and not too hard from there

Simple but beautiful, thank's

A bit challenging but a beautiful end result!

the key on the side looks like a little slime and that makes me happy

Very fun puzzle!

Very hard but well worth it :)

I get that I'm a bit colourblind and need to carefully double-check similar shades... but this puzzle was ridiculously hard! After 7 pages of tiny puzzles without any hints used, I used two here - and the second one completely gave me an entire column and row?
This needs a few distinct-colour pixels to give you starting points to count against, or a few longer rows/consecutive strings so you can place more than 3 pixels down right away!
