Adjusting this value affects the RGB value. Valid saturation values are from 0
to 100%.
Luminance (L)
Specifies the brightness of a color. To specify color luminance, use the color
slider or specify a value in the Luminance box. Valid luminance values are
from 0 to 100%. A value of 0% represents the color black, 100% represents
white, and 50% represents the optimal brightness for the color. Adjusting this
value also affects the RGB value.
Color Spectrum Specifies the hue and purity of a color. To specify a hue,
move the crosshairs from side to side over the color spectrum. To specify color
saturation, move the crosshairs from top to bottom over the color spectrum.
Color Slider Specifies the brightness of a color. To specify color luminance,
adjust the bar on the color slider or specify a value in the Luminance box.
RGB Color Model
Specifies the RGB color model for selecting colors. The options available on
the True Color tab are dependent on whether the HSL or RGB color model is
specified.
Colors can be broken down into components of red, green, and blue. The
values specified for each component represent the intensity of the red, green,
and blue components. The combination of these values can be manipulated
to create a wide range of colors.
Red (R)
Specifies the red component of a color. Adjust the slider on the color bar or
specify a value from 1 to 255 in the Red box. If this value is adjusted, it will
be reflected in the HSL color mode values.
Green (G)
Specifies the green component of a color. Adjust the slider on the color bar
or specify a value from 1 to 255 in the Green box. If this value is adjusted, it
will be reflected in the HSL color mode values.
Blue (B)
Specifies the blue component of a color. Adjust the slider on the color bar or
specify a value from 1 to 255 in the Blue box. If this value is adjusted, it will
be reflected in the HSL color mode values.
