Syntax

public interface ILuminance : IBaseColorField

Lightening or darkening a presentation color in C# runs through ILuminance. The contract represents the luminance adjustment on a color field, the brightness change that makes a color lighter or darker without altering its hue or intensity. A developer reaches for it while building tints and shades of a base color, for instance generating a lighter variant of a theme color for a hover state or a darker one for a border.

A luminance adjustment is obtained from the color it modifies rather than constructed alone, so an ILuminance reference comes from a color and is then set. Its own member is Value, an IPercentage giving how much brightness to apply. Because the contract extends IBaseColorField, it also carries the inherited Modulation and Offset percentages shared by every color-field adjustment. The concrete implementor in IronPPT is the Luminance class, sitting beside Hue and Saturation as the three components of a color tweak, so most code sets brightness through Luminance directly.

luminance.Value = percentage;

The add shape example applies a styled fill, and the paragraph style example shows related color styling.
