Rendered clip color does not match the composition background.

Hi there.
When exporting to AME, the rendered clip looks completely different from my current composition.

Purple tint and glow to text

AME export settings show a black background and lower glow to text.

I've tried messing with project settings and purging cache. No luck yet.

Nothing to do with cahces or whatever. You need to educate yourself about color management, the differences in rendering between 32bpc vs. 8bpc/16bpc and similarly the overall limitations of color ranges in some CoDecs such as H.264/MP4. In your case enabling the "Use Maximum Render Quality" option may be the immediate fix, but there may still be inconsistencies. Again, some of that is to be expected, but the rest depends on your workflow. No simple answers for any of that, even more so since you have not provided any of the relevant details.

Clearly, I need to educate myself, but you don't have to be so passive-aggressive about it. What, you want me to apologize for not telepathically know what details you need in order to help me with the issue? It's not in the FAQ section, I looked.
Regardless, The "Use Maximum Render Quality" didn't solve it. thanks for pointing me in the right direction.

Your cropped screenshot and lack of workflow make it really hard to diagnose the problem. My suspicion is that you set the background color of the comp to the purple tint mistakenly thinking that it would render. If you turn on the transparency grid and you see any transparency in the active camera view the comp will render with a black background on almost all codecs. It's always been that way. The only real reason to set a background color for a comp is to change the color of the edges when you choose Pre-multiplied with Alpha as the color mode and render to a codec with an alpha channel. After Effects and all other compositing apps and NLEs choose straight alpha by default and that is the industry standard. 

If a transparent background isn't your problem we need a detailed workflow description, comp settings, and full render settings.
