Re: Color Palete NUMBERS for a black light.
It won't be a single color, since to render it, you will be displaying a dark bluish purple, with a lighter 'glow' around your rendered 'light source'. Check here:

Hi, Kevin!
Do you think that the values would be So different following the color space?

Yup.
Different gamma settings will give different color numbers for the brightness values, and different specified primarys settings will give different RGB triplets for any given number. Even gray values can be inconsistent, if the colorspace is not gray-balanced, but each colorspace has a DIFFERENT triplet for different colors.
A medium-dark blue that could be part of the glow for a blacklight showed values of
49,143,191 in Adobe RGB(1998)
0,145,194 in sRGB
82,119,173 in ProPhoto RGB
0,127,183 in ColorMatch
All of which are gray-balanced working spaces, and and relatively commonly used working spaces in Photoshop. Those numbers LOOK very much the same, but are only useful when the color space is specified.
So, yes, I do think they're going to be SO different.
