Coloration

A few days ago we saw a noticeable orange slash below the lower-lip (I forget its Latin name) of a RainBow; suggesting a hybrid, wild trout. Then the next day we encounter  a unique Brown with both large, red and black spots...with silvery and blueish halos.

Is this coloration common? Personally I do not see many like this.

And then in the same tail-out...a more common-colored brown eats.
