Changing color of "trackster hits" does not work (for silicon only)

[tcuisset]

When displaying in "Trackster hits" (FWTracksterHitsProxyBuilder.cc), for example collection "ticlTrackstersCLUE3DHigh", changing the color does not update the plot for the silicon sensors (hexagonal), but updates fine for the scintillators (squares).
Below is an example where the entire collection is in blue in the settings but the silicon sensors are still green (while scintillators are blue as they should).
Switching to the next event brings everything to the correct color.

To test: any phase2 sample
(if needed you can use /eos/user/t/tcuisset/fireworks/RelValQQToHToTauTau_14TeV-150X_mcRun4_realistic_v1_STD_RecycledGS_Run4D110_noPU.root with geometry /eos/user/t/tcuisset/sharing stuff/hgcal_fireworks/cmsRecoGeom-Run4_D110.root)

Thank you for the report!
The changes are not propagated to the client when single-color mode is enabled in REveBoxSet.
The way server and client updates are written, the REveBoxset needs to be recreated.

Adding line StampObjProps() in call https://github.com/root-project/root/blob/master/graf3d/eve7/src/REveDigitSet.cxx#L173 fixes the problem.

I will add this change to ROOT.
