[Open Assets] InnocentDalek785's Custom Palette 2.1 - Minor Update

Altered the turquoise section.

Redid the entire palette from scratch.

I edited a certain blue area to make it more distinguishable to the darker sky colors.

That's basically what I did, plus some minor touch ups to the main page.

I edited the orange and pink gradients. Known issue: The skin underside color in some character such as Sonic and Knuckles look too yellowy. This is due to the DOOM engine's limitation of 256 colors only, and the default SRB2 sprite artists used the lightest orange gradient (instead of brown for some reason) for that specific color scheme. There's nothing I can do about this sadly.
