Do you really need URIs?  I.e. do you want to add further descriptions or
links to colors, such as "color1 is nicer than color2", or "color can be
produced from material" – or do you just want to point to colors ("thing has
color")?  In the latter case, wouldn't literals with datatypes be sufficient?
For literals, there is at least a standard for RGB colors: #RRGGBB.  Still,
here it's the standard _datatype_ that's missing.
