The gadget seems to work…but the darker colors look more like anodized metal than enamel paint. (I kind of suck at colorizing anyway, but at least in photoshop you have fine control; here, using CSS and HTML…not so much.) Some not-all-that-exciting details below the more link, if you want them.
When you click on the squares, the colors are changed by, er, changing the color of the sandwich filling, the “sandwich” being the upper slice of bread which is an image incorporating the rock wall, wheels, etc, but with a transparent hole in it where the colored car bits are–and the lower slice, that being a “de-saturated” image that allows the louvers, etc to come through the color.
The color itself is just a plain square of color set with CSS, no images involved. The color list comes from a JSON config file.
Anyway, it’s tedious, and took me way too long to do, but I built it in a way that it could be re-purposed. Though it never will be, in all likelihood, if my career in the software biz has taught me anything. You’re seeing it here in its rawest state, don’t be surprised if I come in and clean up a few things.
You’re looking at colors from the British Standard 381C. Thrilling, isn’t it?
