SPS issues with par

What are signs of too much par? When the coral starts to whiten up? Doesn't look like dead tissue just looks like the color lightened up maybe from high par. You see this when white lights turn on when under blues you can see some color there very faintly if orange glasses put on you can defiant l definitely see color.
 
Generally bleaching is one of the first indicators from my understanding
