Skybox seems to be only using 16bit color?? (picture included)

[acriticalstrike]

whats wrong with my skybox? This is the standard asset from unity sunny2 Skybox. Why does it have this gradient where it almost looks like it’s not using the full color range or something, here’s an image of what I’m talking about:

see all those bars of color change going horizontal across the sky?? How do I make it look smooth like a real sky?

It’s probably a 16-bit colour image instead of a 32-bit one.
