/datum/component/palette	A component that stores colors for use by painting-related items like spraycans or palettes which can be accessed through a radial menu by right clicking the item while it's held by the user mob. Right-clicking a color will open a color input prompt to edit it. Left clicking will instead select it and call set_painting_tool_color() on the parent for more specific object behavior.
