Reversal is not a marking, but a modifier to markings.
Reversal has its own unique way of how if affects which you will find all the information on how it affects each marking style in the specified markings.
In general, it would work that it would do the opposite of what a marking says to do, ie. If a marking states to do darker colours, you would use lghter markings.
However as stated, you would need to check each marking style for any information if it has stated specifically how reversal will affect said marking.
