Brightness appears different in certain colours, this is not down to lower power in certain colours but purely down to the nature of the colour. An Ice Green or an Ice Blue we see as a crisp colour whereas an Ice Purple or an Ice Red we see as a duller colour.
Please remember that colours may look different from screen colour due to the type of photography used.
