Supergel is a variant of Roscolux sold in non-North American markets. In the US, we use the original.
In order to recommend specific colors, we would need to know: type & quantity of
cyc fixtures,
trim ht., distance to cyc, size of cyc. The cyc diffusions can be very useful but in some circumstances, the non-frosted, or the silk, primaries would be a better choice.
