I think you're talking about two different things:

- `srgb` not being allowed in parentheses (same as `rgb`, btw), which is
what you're working around, and which you just /happen/ to need in a
color_map.

- `color_map` always being interpolated in linear colour space, even if
colours are being specified using `srgb`, which I guess is what Mike is
talking about (and which the current 3.7.1 beta solves by providing the
`blend_mode` and `blend_gamma` settings).
