By make and model
The Porsche Club of America launches its Rennbow site -- a catalog of the automaker's historic colors.
More than 500 colors are detailed on the site.
Users can upload their own photos of rare-color Porsches.
The color pages have information about how rare the color is, the models on which it was offered and more.
PCA says it'll offer other color-related feature content on the site, too.
You can search for a color by model.
You can also search for a color by name or hue.
The whole collection can be found at www.rennbow.org.
