Editing colors in HSV

Normal colors
and linked colors
can be edited in several color models
. HSV
is one of these.

To edit a color in HSV

1. Choose Color Editor from the Utilities menu.

2. Choose the color you want to edit from the menu or drag-and-drop it onto the editor.

3. Right-click on the Color Editor and select HSV.

The HSV (Hue
, Saturation
, Value
) model is often found to be the most intuitive color model.

If you select Advanced options you can type in precise values.

To use this color model, choose the Hue from the rainbow colored strip along the bottom. This represents the edge of a circle, hence both ends are red. The Hue is an angle around the circle and can be entered in the Hue field.

The marker in the square panel represents the Saturation and Value components of the color. These values can also be entered in fields under the color strip.

The marker can be dragged and will be constrained to the horizontal and vertical axes if the CTRL key is held down during the drag.

Note

If you are editing a linked color, some of the values will be constrained by white boundaries (shown on the editing area) depending on the inheritance scheme in use. If the Hue has been inherited, the marker on the Hue line will be bound by a white circle and cannot be moved.

The Saturation and Value can be edited in one of two units, percentages (0% to 100%) or values (0 to 255). Which is used is set by the Color Units setting, see Changing the color units. If you need to enter a value in the other format, you can force the units by typing (for example) "25%" (for a percentage) or "25d" (for 0 to 255 value). Hue is always an angle of 0 to 360 degrees.

Many colors on web pages are defined as six hex digits (0-9, a-f). To create these colors in Xara LX use the # box. Letters can be upper or lower-case; "abcdef" and "ABCDEF" are identical colors.
