Colors and colorspaces

Color management presets

Use the cm field to change the default sRGB output preset:

hl.monitor({ output = "eDP-1", cm = "wide" })

Supported presets are:

auto    - srgb for 8bpc, wide for 10bpc if supported (recommended)
srgb    - sRGB primaries (default)
dcip3   - DCI P3 primaries
dp3     - Apple P3 primaries
adobe   - Adobe RGB primaries
wide    - wide color gamut, BT2020 primaries
edid    - primaries from edid (known to be inaccurate)
hdr     - wide color gamut and HDR PQ transfer function (experimental)
hdredid - same as hdr with edid primaries (experimental)

Fullscreen HDR is possible without the hdr cm setting if render:cm_auto_hdr is enabled.

Use sdrbrightness and sdrsaturation to control SDR brightness and saturation in HDR mode. The default for both values is 1.0. Typical brightness value should be in the 1.0 - 2.0 range.

hl.monitor({
  output = "eDP-1",
  cm = "hdr",
  sdrbrightness = 1.2,
  sdrsaturation = 0.98,
})

The default transfer function assumed to be in use on an SDR display for sRGB content is defined by sdr_eotf. The default ("default") follows render:cm_sdr_eotf. This can be changed to piecewise sRGB with "srgb", or Gamma 2.2 with "gamma22".

If your monitor supports it, bitdepth = 10 is recommended for better colorspace handling.

10 bit support

Colors registered in Hyprland (e.g. the border color) do not support 10 bit. Some applications do not support screen capture with 10 bit enabled.

If you want to enable 10 bit support for your display, set bitdepth = 10:

hl.monitor({ output = "DP-1", bitdepth = 10 })

ICC Profiles

You can load an ICC profile via the icc field (path must be absolute):

hl.monitor({ output = "DP-1", icc = "/path/to/icc.icm" })

Please note:

• Path needs to be absolute.
• Having an ICC applied will automatically force sdr_eotf to sRGB for that monitor (for color accuracy).
• Having an ICC applied overrides the CM preset.
• ICCs are fundamentally incompatible with HDR gaming. Funky stuff may happen.
