Colors in the VCL
Go Up to Using the Properties of the Canvas Object
The Vcl.Graphics unit contains definitions of useful constants for TColor. These constants map either directly to the closest matching color in the system palette (for example, clBlue maps to blue) or to the corresponding system screen element color defined in the Color section of the Windows Control panel (for example, clBtnFace maps to the system color for button faces.)
If you specify TColor as a specific 4-byte hexadecimal number instead of using the constants defined in the Vcl.Graphics unit, the low three bytes represent RGB color intensities for blue, green, and red, respectively. The value $00FF0000 (Delphi) or 0x00FF0000 (C++) represents full-intensity, pure blue, $0000FF00 (Delphi) or 0x0000FF00 (C++) is pure green, and $000000FF (Delphi) or 0x000000FF (C++) is pure red. $00000000 (Delphi) or 0x00000000 (C++) is black and $00FFFFFF (Delphi) or 0x00FFFFFF (C++) is white.
If the highest-order byte is zero, the color obtained is the closest matching color in the system palette. If the highest-order byte is one ($01 or 0x01), the color obtained is the closest matching color in the currently realized palette. If the highest-order byte is two ($02 or 0x02), the value is matched with the nearest color in the logical palette of the current device context.
