Fill col with RGBA values corresponding to index ci.
If alpha is true, set alpha component of col to 255. ROOT's indexed color palette does not support transparency.

Find address of Color_t data-member with name varname in object obj.
This is used to access color information for TGListTreeItem coloration from visualization macros that wrap TObjects into REveElementObjectPtr instances.

Return true if interval Q is contained within interval M for U1 variables.
It is assumed that all values are within the [-2pi, 2pi] interval and minM <= maxM & minQ <= maxQ.

Tweak all ROOT colors to become brighter (if value > 0) or darker (value < 0).
Reasonable values for the value argument are from -2.5 to 2.5 (error will be printed otherwise). If value is zero, the original colors are restored.
You should call REveManager::FullRedraw3D() afterwards or set the argument full_redraw to true (default is false).
