Ah. There's a much easier way to do that:
Put the colour layer down, then make a new layer filling it with white and select the blending option "Saturation". This makes the layer below black and white. So then you can simply move this white layer to the side instead of deleting it bit by bit.
Btw I didn't realise that you actually made them from 1-100. That must have been a grueling process!
