Just want to point out to those reading the back and forth here about hue angles, that the Photoshop hue doesn't necessarily bear a direct relation to the NTSC chroma phase angle. The color produced on the screen for a given NTSC phase angle varies depending on the brightness and saturation of the color, due to the CRT gamma characteristic (non-linear response of light output vs. drive voltage).
This illustration "NTSC Color Television Standards" shows how the hue varies with saturation for a given phase.
+I is at 123 degrees (electrical) which clearly is not a straight line on the chromaticity diagram.
