ColorMGR v2.3
Sick of changing colors on components one at a time?
Tired of trying to find those RGB values?!?
ColorMGR(color manager) is a simple and easy to use color management and swatch creator. It provides Unity developers with an efficient workflow for creating consistent color across multiple projects and between multiple developers. Keep your project’s color palette at hand and never hunt down color information again!!
> Create, name, and edit swatches using Unity’s color picker.
> Include an unlimited number of swatches in your color palette.
> Export color palettes (to a text file) and import them into any Unity project.
> Use the ”apply to” feature to apply colors to specific components of any number of selected objects.
>Export swatch as a script. Now a single swatch can be exported as a script and applied to object at run-time. Great for procedurally generated content!
>Full NGUI and Daikon Forge GUI support. Use the “Apply To” feature to change color on multiple objects for both NGUI and Daikon Forge UI. All properties are exposed for both of these GUI editors.
