Here's the scenario:

I have a B&W-ized photo, and I have coloured it in using multiple 'color' layers.
I now want to change some of the colours.
I select the layer using 'alpha to selection'.

Now someone tell me how to change the colour.

Is there an easier way than to use 'colorize'?

with masking?
