Very satisfying. Mmmmmmmmm.

The puzzle is very nice and well-constructed, but it was a bit hard for me personally to differentiate between so many different colors.

Love this. For me it makes a good intro for the Colorado series as its a much more approachable puzzle that teaches you the same techniques.

Experience told me to start coloring instantly. Great fun thx.

great puzzle, really enjoyed the solve!

Very nice puzzle. As the others have commented, the negative constraint does not appear to be necessary to solve. It was still a fun puzzle, and a good coloring exercise.

I LOVE these color puzzles so much--thank you for making it and titling it as one. Definitely used the colors and it was a delightful solve!!

Yeah this was half an hour for me, I coloured the entire thing with parity but then I had to do some thinking to know what goes where, but once you got some, the whole thing just resolves very cleanly! Very nice

very enjoyable, love a colourful grid. didn't even read the negative constraint, worked well without it

Cool puzzle.
I found it easier to use letters instead of colors because it got too confusing

Very nice puzzle. Fun solve. Thank you. I didn't even realize there was a negative constraint until after I finished the solve and read through some of the comments. So it's definitely not needed. But...it took me significantly longer than it seems other people needed. So maybe I would have finished in less time if I'd been aware of the negative constraint.

36:26. I may have gotten a bit color-happy, but I ended up with a beautiful grid and a quick solve after the break-in. Fun puzzle :)

That was fun!

Loved the logic used to start off the puzzle! Really clever negative constraint.

32:04...I worry I overdid it with the coloring and that got my brain more confused than without it. I also worried that the logic I did end up using to disambiguate the colors was wrong, but it led me to the right solution based on the code, so I guess I learned :)
I agree with the others the negative constraint isn't necessary, I used it very briefly in one spot but it didn't relate at all to how I solved the rest

As a beginner who's just trying to learn from the easier puzzles, this was a lot of fun, thanks!

Wow!

I found that one little slip of concentration and you have to backtrack quite a bit. :)
It was fun!

This definitely is a good tutorial on coloring.

I forgot about the negative constraint
I solved it just using coloring
Beautiful puzzle

Solved it using the negative constraint. Then read the comments and solved it again without using it. It's about the same either way. Very fun, thanks!

Very nice and very easy puzzle. Love these easy puzzles that take a little time to do. Not to fast and doesnt take too long either. Perfect for a relaxing morning solve! thank you!

i did the whole puzzle without realising there was a negative constraint but i feel like it would have saved me some solve time
on 29. September 2023, 17:37 by Kirra
Nice puzzle. Would be a great introduction to colouring for someone new to the concept :)
on 26. September 2023, 02:52 by cascadeshiker
Thanks for the puzzle. I think I prefer using letters to colors though.

Thanks for this! I love when numbers can be filled in 9-at-a-time.
on 9. August 2023, 16:49 by DonQuichopp
at first it blew my mind. Didn't know where to start. Once understood, it was great fun to solve it.
Thanks a lot!

Great quick puzzle. I agree about the negative constraint, I didn't pay attention to the rules because I was in a rush and didn't realize there was a negative constraint until I was inputing the solution code, so I didn't use it at all. Still solved it super quickly.
on 26. July 2023, 18:36 by Ryx
Wonderful puzzle. I didn't feel like there was any conundrum at all, once I found the right place to start coloring ;-)

Cute. I agree the negative constraint wasn’t needed, but it was a handy shortcut once or twice.
on 25. July 2023, 23:58 by Silverscree
4:28, nice quickie. I agree that the negative constraint adds nothing, but I thoroughly enjoyed speedrunning it

Fun!
on 25. July 2023, 19:13 by timyoth
nice little snack. The negative constraint is not needed tho.
on 25. July 2023, 19:02 by SHERAX
Once you found it it solves fast!

As close to a LSD-trip as a sudoku can probably get!
Had great fun, thanks for setting!
on 25. July 2023, 12:22 by zrbakhtiar
yup. as intended, indeed an nice working intro to coloring. next step, double colouring. +lettering. haha.
on 25. July 2023, 10:07 by Ratfinkz
Lovely smooth solve! I did use the negative constraint a few times!
on 25. July 2023, 02:46 by rpearl
I did not appear to need the negative constraint on XVs?
