Ink color code chart from the Technical Manual

Here's a list of color codes for the RP series (should work on all models, have been tested on a RP3100UI and RP3700).

Unlike with newer machines which use chips to show the appropriate color on the Riso, the ink must be manually dialed in on the RPs through a Test Mode setting. It is however not necessary to change the color code on the drum after swapping ink colors but if you want the Riso to show the corresponding drum color on the display, you can use the codes to update the drum settings after changing inks.
