You are not using the correct ranges for the color values. You are
assuming that they lie in the range 0 to 255, but that is not the
case.  See "DeviceRGB color space" in 4.8.2. Each color space may have
different colorant ranges.

You may have seen 0..255 in RGB PostScript images, but this is just a
representation to be scaled to the true value using the (supplied or
default) Decode values. It would be 0..15 in a 4-bits-per-component
image, to represent the same range of values.
