A few years ago I orded this RAL color reference chart of 215 swatches from Amazon that includes the four digit color code sytem printed on the back of each swatch. These are the same codes used on the SQ2 configurator when ordering a finish.
For those who are considering ordering a custom kit with an RAL finish, something like this may be a wise purchase up front before ordering your drums to verify it's actually the color you want.
