Light is only one factor that effects color fading.

Dye inks can "out gas" changing color left on paper.

Temperature is a big factor for out gasing. Higher the temperature faster it will happen.

Paper can yellow, its OBAs out gas.

Inks (dye and pigment) can react with other airborne chemicals. Temperature is again a factor.

As you see, light is only one of many factors.

If you substitute gas fading or oxidation for every spot you used "out gas(sing)" then it makes sense. Or just keep the last two lines of your message and delete the rest. In inkjet printing terms "outgassing" is used for the evaporation of the ink medium components glycol and glycerine from a fresh print. With RC prints this can take a long time and if not cured long enough before framing a haze can condensate at the inside of the frame glass.
