Intensity of light from a hexadecimal value of color

In physic unit of light is the Candle.

I already have the hexadecimal value of a color for instance #030101, but i want to know Light intensity of every color. How can i get it?

Is the concept of Brightness in Photoshop trying to model Candel for computer?

No such conversion is possible. The actual intensity will depend on settings on the output device, such as the brightness setting on the monitor, and the color space being used.

There is an abstract intensity measure in the HSB color model, but it just specifies a value between 0 and some arbitrary upper value (i.e. 0.0 to 1.0 if using floats or 0-255 for a typical color picker). The two extremes represent only "the darkest color possible" and "the lightest color possible", both of which depend on the output device and have no absolute meaning in terms of candelas.
