Functions

get_slot_color

Retrieve's the color of a certain slot/category in any color format (default hex), formerly known in english as Weapon, Vitality, and Spirit, though their unlocalized names are Weapon, Armor, and Tech. Utilized by Template:SlotColor

Parameters

• slot - slot key, options are Weapon, Armor, and Tech
• color_format - color format - Defaults to hex. Valid options are hex, rgb, hsl, cmyk
• no_wrap - (OPTIONAL) - Defaults to false. Set to true to remove prefixes and postfixes of '#' from hex, or 'rgb()', 'hsl()', and 'cmyk()' from the other formats. May be useful for altering the values dynamically
• debug_mode - (OPTIONAL) - Defaults to false. Used mostly for documentation purposes
