Found to have a unique solution by blurglecruncheon.

Found to be solvable by line and color logic alone by blurglecruncheon.

This is a weird one because it's hard to know where to start.

For those who don't want to use edge logic at all, look at column 23. Where does the blue 1 go? It can't go in row 12, as then C19/20 would be blue. So it must be row 19 or below.

From there the line and color logic are pretty straightforward. (I think.)

Yes! Cool activity!

Actually, I was looking at the first few columns and rows when I solved it. Columns 2-7 and rows 2-7 have to include all the blue in those columns and rows, thus bounding those clues into a 6x6 box. With the 3/1/1 and 1/3/1 from columns 4 and 5, as well as rows 4 and 5, they require 5 out of the 6 spaces, thus allowing me to place 2 spaces from each 3. From there, line logic allowed me to fill in the rest of that 6x6 area.

After that, I was able to use line logic to place the larger green numbers, and more line logic to intersect with those, gradually filling in the rest.

On top of all this, I also noticed that the horizontal clues are exactly identical to the vertical clues, which means the image was perfectly symmetrical across the diagonals, making it even easier to complete the rest of the line logic.

Nice kayak! I noticed the diagonal symmetry, too, which helped imensly, but that start though...

phew, that was a tough start. I was stuck with about 6 blue and 4 green placed for a while before I got it moving. Pretty easy after that. Nice image!
