Don’t understand why photoshop creates strange color noise when colorizing a B&W photo. The attached sample should not happen as pure colors should not be generated but wondering if there is an easy way to get rid of them? Tried “Color Range” but it not great.

There are techniques to alleviate color noise (like using a filtered Smart Object copy set to Blend Mode »Color«), but please provide the additional information @Brad @ Roaring Mouse has asked for.

In my opinion Photoshop’s »Match Color« is worthless because it is destructive – which is not to deny that it may serve you perfectly well (except in this case apparently).

How exactly are you doing this? i.e. what steps are you using to colorize?

Adjustments/Match Color. Have seen it many times before and there are videos on Youtube about it.
