custom crayon color labels

Not too long ago, Heinz ketchup started selling custom-labelled bottles of ketchup. Those bottles were more expensive than standard ones, but not prohibitively so, and they looked pretty good - better than what I could have faked.

I would like to see that technology applied to another target: crayons. Allow consumers to order small color sets, chosen from a larger portfolio of preexisting colors (this part exists), and make up their own names for the color labels on the crayons. Everything else is exactly as with the standard crayons.

For example, let's say your daughter's name is Vivian, and she has dark brown eyes. The set of crayons she gets for her birthday might contain a dark brown shade labelled "Vivian's Eyes", a dark green labelled "Ick, Spinach", and a reddish brown shade labelled "Peanut" (after the cat.)

Or, if you're planning a gift for xenzag, there would be a full set of warm greys labelled labelled "dishwater 1" through "dishwater 9".

Companies can print custom crayon wrappers in large scale as give-aways, but I haven't seen this as a retail application.
