Change background color

I feel stupid, I googled it, but I can’t find it. I want to change the backgroound color to magenta, right now it is black… this could save me a lot of time during rendering animations…

I tried changing every setting in the world settings to magenta… no luck.

Surely it is easy, but I can’t find the color slider for this function.

Most likely you have “Premul” turned on in F10 - By the nature of premultiplied alpha images the background comes out black.
Set it to “Sky” if you want the object to be anti-aliased against the background, or “Key” if you’re going to be using the magenta for colour-keying.

thank you thank you thank you…
