Summary

Function: llSetColor( vector color, integer face );
0.0 Forced Delay
10.0 Energy

Sets the Blinn-Phong color on face of the prim.

• vector color – color in RGB <R, G, B> (<0.0, 0.0, 0.0> = black, <1.0, 1.0, 1.0> = white)
• integer face – face number or ALL_SIDES

If face is ALL_SIDES then the function works on all sides.

Newbie Notes

llSetColor changes the color of a prim, either on a specific side (face) or the entire prim.

Example: 
llSetColor(<r, g, b>, ALL_SIDES);

r, g, b: values for red, green, blue ranging from <0.0, 0.0, 0.0> (black) to <1.0, 1.0, 1.0> (white)

To continue reading see: Newbie Notes

Caveats

  • The function silently fails if its face value indicates a face that does not exist.
  • llSetColor will have no visible effect on faces with a PBR material. To work on faces both with and without a PBR material, use this snippet: 
    llSetColor(color, ALL_SIDES);
llSetLinkPrimitiveParamsFast(LINK_THIS, [PRIM_GLTF_BASE_COLOR, ALL_SIDES, "", "", "", "", llsRGB2Linear(color), "", "", "", ""]);

Examples

integer face = -1;
vector color = <1.0, 1.0, 1.0>;

default
{
    touch_start(integer num)
    {
        if(~face)       //quick & dirty but efficient way of testing if face is not equal to -1
            llSetColor(color, face); //restore the color
        face = (face + 1) % llGetNumberOfSides(); //increment and keep the face number in range
        color = llGetColor(face); //save the face's color
        llSetColor(<0.5, 0.0, 0.0>, face );  //change the face's color
    }
}
