Hi, here's my wallpaper submission, it comes in 2 versions :
1)

2)


Full size(4000*2250) :

These are nice entries, however the colors are a bit bright and neon-ey. If you imagine minimizing a maximized window, suddenly your field of vision is filled with this super bright color as the desktop wallpaper comes into view. Making the colors a bit more pastel and less neon might mitigate this effect a bit.

Thanks for the feedback, here are the pastel versions :

Thanks, those are quite nice! I especially like the subtle purple elements on the cool-colored version. A bit of that on the left-hand side of the warm version might look good too.

Here's a purpleish version of the warmth one :

Nice work on the last version, what makes it better its that it's not 2 colors anymore per se.
