Standardize color usages

[CodeSpent]

Colors in the site have undergone a lot of temporary tweaking with a lot of reference from the Unicorn Utterances application in order to get off the ground faster with theming.

The time has come to standardize a lot to do with colors including;

• Organization of the colors & keeping them DRY so when theming there isn't a need to modify multiple values. This also improves debugging woes.
• Correct usage with Tailwind patterns & using utilities provided.
• Establishing an actual theme using the colors present as backgrounds, accents, neons for bars, etc.

This is something I had planned to tackle, but also recognize it could be an opportunity for a Hacktoberfest contribution so I'm opening to the public.
