{
Here's some function that returns the lighter or darker color of a TColor.
You can use it, for example, to design a bevel or something like that.
}
{=======================================}
function Min(a, b: Longint): Longint;
begin
if a b then Result := b
else
Result := a;
end;
function Max(a, b: Longint): Longint;
begin
if a b then Result := a
else
Result := b;
end;
{=======================================}
function GetHighlightColor(BaseColor: TColor): TColor;
begin
Result := RGB(Min(GetRValue(ColorToRGB(BaseColor)) + 64, 255),
Min(GetGValue(ColorToRGB(BaseColor)) + 64, 255),
Min(GetBValue(ColorToRGB(BaseColor)) + 64, 255));
end;
function GetShadowColor(BaseColor: TColor): TColor;
begin
Result := RGB(Max(GetRValue(ColorToRGB(BaseColor)) - 64, 0),
Max(GetGValue(ColorToRGB(BaseColor)) - 64, 0),
Max(GetBValue(ColorToRGB(BaseColor)) - 64, 0));
end;
