That's just how Filmic color management works. In order to support displaying values > 1.0 without clipping, 1.0 needs to be pushed down to make room for such HDR values.

@brecht: Should the color swatches not take color management into account? Right now they seem to be hardcoded to use Filmic always, even if you don't use Filmic. That seems wrong, surely?

@brecht But:

It doesn't reach 255 in sRGB display transform.
There is no slider to go beyond 1.0 if setting HDR color is the point. Which it probably is not, given 1 is "absolute" reflectance, which is how majority of material color settings are used.
Normal monitor isn't capable of displaying HDR. Pushing the value down is limiting the already very limited resource of color gamut.
Normal monitor is not able do display sensible hdr even if color is being pushed down like this. Meaning - it gives 1, max 2 additional stops with a highly trained eye. One can't tell what color it actually is and at what luminance beyond that.

Imho applying color transforms to swatches is a huge can of worms that requires big consistency investment. For example - you have to differentiate reflective color settings vs light color settings etc., otherwise there is a loss of both - precision and intuitiveness of color control, which is kind of a big deal.
Edit: that might be ok for Filmic, since it is beforehand assumed that what you see is not what you get, but not somewhere else.

First let's be clear about terminology. There is an sRGB display device and a Default or Filmic view transform. That it uses Filmic even when disabled is a bug.

We would like to add the distinction between albedo and emissive colors at some point, but that's outside the scope of the bug tracker.

Sorry, I should've worded that clearer.
Color type differentiation sounds intriguing :)
