*When working with templates, I use the Manual Color
Correction Tool (MCCT):
Highlight template layer
Click on the MCCT
Set top box to original layer color
Set bottom box to new color
If you want to use the same color with different shades,
simply click each template layer and apply the MCCT
WITHOUT changing the bottom color. This usually works giving
each layer a different shade of the same color.
Occasionally you will find a template that this will not
work on tho, so in that case simply change the colors each time.
This works great on templates with different shades of Gray
There is a great mini-tut on how to use the MCCT by Justfi HERE
Another way to color template layers:
When working with templates, always Shift+D to duplicate,
then on each layer, select with magic wand (or Select All,
Float, De-float), ANL,
close/delete the original, do steps required in tutorial,
Try it out and see what works for you.
