Shift Colors

The Shift Colors sub-menu of the Effects menu contains the following adjustment color filters:

Black and White

The Black and White color filter (Effects - Shift Colors - Black and White), converts the colors to a monochrome tone (by default black), using weights of various primary colors.

The color tone, is determined by the amount of Red, Green, Blue, Cyan, Magenta and Yellow tone of the colors. These color amounts participate on the resulting tone with a user selected weight.

The resulting tone is then converted to a monochrome gray tone, or to shades of a color or a gradient.

The Black and White color filter editor.

  • Green - Edit the weight of the Green color in the resulting tone.
  • Blue - Edit the weight of the Blue color in the resulting tone.

Channel Mixer

The Channel Mixer color filter (Effects - Shift Colors - Channel Mixer), converts the colors to a target color mode, from a source color mode, by using parts of the source color channels, to set the target color mode channels.

Each color channel of the source color mode can partially contribute to a target color mode channel. The amount of these contributions are set by the user, for each combination of target and source color mode channels. The contrast of the color in the source color mode can also contribute to the color channels in the target color mode.

Alternatively, it is possible to mix the colors into tones of a single color, or colors from a gradient transition, using the Tone option.

The Channel Mixer color filter editor.

  • Source - Select the source color mode. Colors are first converted to this color mode, and then the color channel amounts are used to calculate the target color mode channels.

  • Channel - Select a color channel from the target color mode, to set the source color channel amounts.
