Retaining colours after colour to alpha
#3
Blighty has given the start again from beginning, however

The way you describe is a terrible way of removing a background, so the rescue mission

You did something like this. Rough select, cut, http://i.imgur.com/JmBS9Qc.jpg then color-to-alpha to remove all white

It is possible to select areas of 'alpha' much the same as any color. Use the fuzzy select tool, put it in add mode put the threshold right down (zero-ish) and click in individual areas to build up the complete selection. http://i.imgur.com/ZGXYjI8.jpg

Grow that selection 4 or 5 pixels and invert.

A new transparent layer under, fill the selection with white. http://i.imgur.com/TxhJaa9.jpg

Save your work as a gimp .xcf for any editing in the future. Export as a png for a 'flat' file with transparency.
