[chimerax-users] change color for map slices

Dear chimeraX team, I have some issues when coloring a cryo-EM map. I firstly colored a map gray, then fitted the models in the map and colored the map by zone. I'd like to generate a cross-section slice, but the slice color is always white. Please see the attached image for example, the green surface color is good, but the slice is white. Is there a feature I could use to cap the slices with colors? Thanks. Best wishes, Miao
