Change the bulbs to a warmer LED light maybe 3000K probably just have crappy bulbs.

As RL says. Use the plug--and-play LED tubes designed to replace fluorescent tubes. several color temperatures are available online.

Do you hate the quality of the light or the look of the fixture?

I really don't like the look of the fixture and this is nitpicky, but I also don't like the buzzing sound Fluorescents make.

You can get flat-panel LED fixtures, about 12" x 48". The color temperature of the ones sold by Lowes are changeable. They're not cheap, however, about $100.

I had no idea you could get LED bulbs for them! Great!

You can remove that and replace with any fixture you like a bit of ceiling patch and a coat of paint Yes the LEDs are great if you just want the type of light changed they also do not flicker like the old ones.

Fluorescent lights require a ballast. You can buy a plug-and-lay LED tube bulb that will work with a compatible ballast or modify the light's wiring to bypass the ballast an buy a direct-wire bulb. It's described here which also explains color temperature.
