The colour picker allows you to pick colours from a 16-bit floating point media. It also displays additional information to accommodate the wide range of possible values in 16-bit floating point.

Whenever you set the Bit Depth box to 16fp:

• Each colour slider contains a pair of brackets. The brackets define the 0-1 colour range. Only values inside this 0-1 range are valid once converted to a 8-, 10-, and 12-bit colours.
• You can set values below 0 or over 1. Such values are only possible in the 16-bit floating point colourspace and are not valid in 8-, 10-, and 12-bit colours.
• The numeric fields can use negative values.
