We have four main colors used throughout our app. The exact RGB value of these may be tweaked as we go through production. Our work would be made easier if we could define these RGB values in one place and reference these definitions where we use the colors (to tint a box for example). In our GUI file, instead of doing
color { x:0.95 y:0.3 z:0.0 w:1.0 }
we would do something like
color { ELEMENTAL_COLOR_FIRE }
Currently we can do something like this at runtime by querying and tinting on init. But not having the colors show while editing game and GUI objects makes it a less than ideal solution.
