The D3DCOLORVALUE structure describes color values for the D3DLIGHT2 and D3DMATERIAL structures.
typedef struct _D3DCOLORVALUE {
union {
D3DVALUE r;
D3DVALUE dvR;
};
union {
D3DVALUE g;
D3DVALUE dvG;
};
union {
D3DVALUE b;
D3DVALUE dvB;
};
union {
D3DVALUE a;
D3DVALUE dvA;
};
} D3DCOLORVALUE;
You can set the members of this structure to values outside the range of 0 to 1 to implement some unusual effects. Values greater than 1 produce strong lights that tend to wash out a scene. Negative values produce dark lights, which actually remove light from a scene. For more information, see Colored Lights.
