No idea, just some guesses for you to test out.

Replace Color_Yellow directly with a code like 0xFFFF00AA
Try creating the 3d text label without the streamer ( Create3DTextLabel )

So it would be something like this:

PHP Code:

Create3DTextLabel("Don't Forget to read rules.", 0xFFFF00AA, 1467.841308, -1256.526367, 14.571758, 98.0136);
