+>Palettized (8-bit) screen surfaces with the
+<TT
+CLASS="LITERAL"
+>SDL_HWPALETTE</TT
+> flag have two palettes, a logical
+palette that is used for mapping blits to/from the surface and a
+physical palette (that determines how the hardware will map the colors
+to the display). <A
+HREF="sdlblitsurface.html"
+>SDL_BlitSurface</A
+>
+always uses the logical palette when blitting surfaces (if it has to
+convert between surface pixel formats). Because of this, it is often
+useful to modify only one or the other palette to achieve various
+special color effects (e.g., screen fading, color flashes, screen dimming).</P
+><P
+>This function can modify either the logical or physical palette by
+specifing <TT
+CLASS="LITERAL"
+>SDL_LOGPAL</TT
+> or
+<TT
+CLASS="LITERAL"
+>SDL_PHYSPAL</TT
+>the in the <TT
+CLASS="PARAMETER"

+parameter.</P
+><P
+>When <TT
+CLASS="PARAMETER"
+><I
+>surface</I
+></TT
+> is the surface associated with the current
+display, the display colormap will be updated with the requested colors.  If
+<TT
+CLASS="LITERAL"
+>SDL_HWPALETTE</TT
+> was set in <A
+HREF="sdlsetvideomode.html"
+>SDL_SetVideoMode</A
+> flags,
+<TT
+CLASS="FUNCTION"
+>SDL_SetPalette</TT
+> will always return <SPAN
+CLASS="RETURNVALUE"
+>1</SPAN
+>,
+and the palette is guaranteed to be set the way you desire, even if the window
+colormap has to be warped or run under emulation.</P
+><P
+>The color components of a
+<A
+HREF="sdlcolor.html"
+><SPAN
+CLASS="STRUCTNAME"
+>SDL_Color</SPAN
+></A
+> structure
+are 8-bits in size, giving you a total of

+does nothing, returning <SPAN
