Data Colors in Treemap

Data Colors within Treemap should offer color palettes to select from and/or offer gradients of colors that can be excluded from being used in the display.

Depending on how data is filtered, sometimes odd colors are automatically applied that make the data unreadable (like neon green with white text labels).

I understand each color can be customized, but when the data colors change based on a broad series of possible filters on the page, it's not possible to customize every option in advance.
