add color palette

[Lykhoyda]

Closes #191

[Lykhoyda]

@Tbaut Some colors could still be hard coded as they are not from the primary color palette introduced in the design (I will handle it in the next issues dedicated to the update of the specific component).

@asnaith Please check if any element looks off after the colors update

This is awesome, thank you so much. Very clean already. I've been looking carefully at the buttons, the text fields, and most of what should have been impacted, but I let Andrew take a closer look to, I'm never too sure :)

This is a really nice improvement @Lykhoyda, I couldn't find anything that looked off.

The color has added a nice consistency and the depth on the multi/proxy badges really stands out now
