Union tricks?

A while back, I thought it might be handy to represent a ARGB Color as a BYTE[4], a DWORD, and A/R/G/B. I built his union: typedef union _Color { struct { float a, r, g, b; }argb; DWORD dwColor; BYTE ColorArray[4]; }Color; It did come in pretty handy, but there''s one little nagging thing. Accessing the components means I have to go thru the struct, i.e. SomeColor.argb.a = //something Is there anyway to remove the struct from it or somehow make it invisible? I don''t want a, r, g, and b to occupy the same memspace; they should be a struct. I want to do something like omeColor.g which is a little shorter and cleaner. Is there anyway to do this?

Or it could mean your monitor''s gamma sux0rs. 3 bits of color is all anyone ever needed.

No, just the dim half of the EGA colors (3-bits = 8). The bright colors were obnoxious.

I remember how ecstatic I was when I got my first EGA card and got to see King''s Quest in 4-bit color instead of monochrome.
