Seqüence Environment [Sampling] FX Buy

Hello, how to enable more colors for the arrangement environment instead of only the colors of the rainbow? I can’t enable even the grey matter… Maybe It is suppost about the locking event I told before in other post. But maybe it are only not available or viewable from the source version now. Why? I don’t know, mistakes… if… But where to do?

Can I launch something else without ask what to do or checker flag?
