 Whether the colour is perceived as darker or brighter
depends on the user's colour vision.  Unless the brightness
contrast is high, you can't be sure.
 As a rule of thumb, you can assume that most colour blind
people perceive red as equally bright or darker than 
normally sighted people do.  If the red colour has lower
brightness, the colour blind will perceive it as darker.
However, this may make it harder to read.

 Colour blind people don't have black and white vision.
(except in some really, really rare cases)  They just
have more or less distorted colour vision.
 You may think red is generally brighter than blue. 
But that's not how many colour blind people sees it.
