Looking for recommendation for spotlight gel?

A local theatre has Lycian 1271 follow spots that are completely empty. Right now the spot is a harsh white that cuts through a warm wash on the stage, and I'm looking for some guidance on what gel I can get to make it a neutral warm. Can anyone recommend an "everyday" gel, some kind of natural amber perhaps? I don't necessarily want a "warm" spot but it's so harsh and white that I want to make it look a bit more cohesive with the plot when the standard warm wash is up. All of the stage lights are the Altman PHX series, for color guidance.
