Don't worry - you'll soon find that creating and solving pbn will make your brain smarting!

Enjoyed the image, but it took alot of guessing to get there.

It’s my eyes that hurt after a while. Good solve.

I switched over from clicking on the squares to hovering the mouse over a square and using the fingers of my left hand on the 12345 keys to select what to fill in in that square, and that is a lot gentler on my mouse hand. If you hold down the 1 key while you mouse over a square, that puts a dot there. 2 is black, 3 is red, 4 is green, and 5 is blue. Also the h key fills in the whole line horizontally, and the v key fills in the whole line vertically. This is much less clicking, and my hand is a lot happier!

I'm sure a lot of people already do this, while a lot of other people have no idea that it's an option.

Difficult. Had to use deep lookahead multiple times. First on the rightmost 2 in row 21. Either way it can go it gets you a lot of squares, and then gets it. Then the 4 in column 20 gets you most of the right of the puzzle. Then the hardest part, the first 4 on the bottom row. There are two spots it can go. You know which one it is, but proving the other is wrong is tricky. Finally, the second four in row 25.
