Specifying Colors
Description
Alpha Anywhere provides extremely fine control over colors when you set the properties of object on layouts, or when you specify a color in an Xdialog form.

Specifying a Color
You can specify a color in two ways. If the color is a named color, you can do this.
{background=Red}If there is no named color available, you can specify the color's RGB values.
{background=#247,227,144}Specifying a Relative Color
Given a color, you can modify one or more of its values. The syntaxes are (remove all spaces in the final version):
+|-Symbol Amount Color_Name +|-Symbol Amount RGB_Value
Symbol is a value from the table above. Amount is a value within the appropriate value range. For example, reduce the luminosity of "Red" by 10.
{background=-L10Red}Increase the hue of color "#60,180,30" by 25.
{background=+H25#60,180,30}Specifying an Absolute Color
Given a color, you can set one or more of its values. The default color is "Black", which is "#0,0,0". The syntaxes are (remove all spaces in the final version):
##Symbol Amount [ +Symbol Amount [ +Symbol Amount [ +Color_Name ]]] ##Symbol Amount [ +Symbol Amount [ +Symbol Amount [ +RGB_Value ]]]
For example, start with the color "Red" and set its blue component to 50 and green component to 25.
{background=##B50+G25Red}Starting with the default color "Black", define the color that we call "Blue" by setting its hue to 240, luminosity to 50, and saturation to 100.
{background=##H240+L50+S100}Combining Relative and Absolute Syntaxes
This example takes "Light Blue" and decreases the hue by 25 and sets the luminosity to 75.
{background=-H25##L75Light Blue}Limitations
