If you want to set a component (e.g. RED) to zero, use these mul: 0xFF00FFFF add: 0
If you want to force a component to be full-on (e.g. BLUE), use these mul: 0xFFFFFFFF add: 0x000000FF If you want to slightly darken RED and GREEN, use mul: 0xFFCCCCFF add: 0 On Tue, Feb 10, 2009 at 3:41 PM, myIP <marckas...@gmail.com> wrote: > > Mike, thanks for the reply.
