During the long history of MIYUKI, many tentative color numbers (e.g. number +R, +S, +F etc.) were created for some beads. It turns out that some bead colors have multiple color numbers even though they are the same color.
We would like to standardize our seed beads color numbers by unifying these multiple color numbers into single color numbers in order to make our color No. more friendly.
Also there used to be dedicated color numbers to the specific shapes and sizes. For example, color 701 used to be indicated for Round Rocailles 8/0 silverlined cyrstal only.
The below Standardizing color conversion chart is for tentative / dedicated (as called Old Color No.) and their unified color No.
Note: Delica Beads and Triangle Beads are exceptions.
