Color Inputs: Allow for colors in all spaces

[tylergaw]

For the MVP, we're only able to input colors in hex format. That drastically limits the usefulness of the tool.

Instead, we need to implement a custom text input and color picker that allows for input colors in all (or most) spaces. Including, but not limited to:

• rgb
• lch
• oklch
• lab
• oklab
• hsl
• hwb
• p3
• xyz

There are more. Some of these are still hazy to me, so I'll be taking cues and inspiration from other tools doing this already like https://gradient.style and https://colorjs.io/apps/picker/p3
