Viewing and Setting Channel Values

You can use options in the Mode box to view and set the colour values for the individual channels of the current colour model.

To view and set channel values:

From the Mode box, select one of the following options.

Select:	To:
Clr	View and set the colour values for the individual channels in terms of real values (0-255).
Clr %	View and set the colour values for the individual channels in terms of percentage (0-100%).

Select a colour model from the Colour Model box.

Select:	To:
RGB	Display the red, green, and blue channel values of a colour.
YUV	Display the luminance, U-chrominance, and V-chrominance channel values of a colour.
HLS	Display the hue, lightness, and saturation of a colour.

Set the value for each channel using the slider bar, the numeric keypad, or the colour picker:
- To use the slider bar, press on a slider bar and drag it up or down. Dragging with the left mouse button changes values more slowly than dragging with the right mouse button. If you are using a pen, apply more pressure to increase the rate at which values change.
- To use the numeric keypad, click the channel value at the bottom of the slider bar, and enter the value.
- To use the colour picker, click Pick, and drag the colour picker along a channel or an image until the required colour is displayed.
The colour pot in the upper-right corner of the colour picker interactively updates as you change the channel values.
Do one of the following:
- Transfer the colour to the Current Colour pot by clicking it.
  The selected colour becomes the current colour in both the colour picker and the colour pot you originally clicked.
- Transfer the colour to the colour palette by selecting Pot in the Mode box and then clicking and holding on a colour pot.
