Reading the Color Space Charts
Mass Tone 1% (a*/b*) — shows each pigment at full masstone strength. MX-2952 and MX-2908 sit at the redder, lighter end (a* ~17–19, b* ~-44 to -45), while MX-2962 and MX-2905 trend bluer and deeper (b* down to -49/-50). CI-2900 sits in the middle of the pack at a* ~17, b* ~-47.
Tint Tone 1:5 (a*/b*) — the same pigments let down 1:5 with white, which is often more decisive for matching. Here CI-2900 reads bluest (a* ~2.2, b* ~-29), while MX-2962 shifts noticeably redder and deeper in tint (a* ~3.6, b* ~-33) — useful if a formulation needs to hold its blue character after dilution rather than drifting.
Note: the chart data also includes MX-2905, MX-2956, and MX-2956 (LS) — grades not listed on the current shade card — worth confirming before publishing if these are meant to be part of the same line.
Choosing a Grade
