Thanks. I have that already and it doesn't give the same effect. Even creating a copy of the image with just a splash of colour in one place e.g. a hat then using the color match plugin on a greyscale copy doesn't end up with the hat coloured. You end up with the colour bleeding into most of the image as that plugin is really just looking at the whole palatte rather than individual regions.

I have been doing a lot of looking around for an easy way to recolour black and white photos. Today I came across this paper from 2005 that allows you to recolour image by just painting stripes! http://www.cs.huji.ac.il/~yweiss/Colorization/ There is Matlab code there and I found a GIMP plugin source here https://bitbucket.org/grimboy/colorize-gimp/src, although I couldn't get the GIMP plugin to work. I found a standalone implementation that I was able to get to work: http://users.eecs.northwestern.edu/~mya671/Colorization.htm It would be awesome if someone could implement this for Paint.Net!

I have some black and white photos from my wedding and I want to add some colour to them. It looks like it will be too much effort to recolour the whole photo so I might settle for just colouring the waistcoats for a splash effect. I have read lots of tutorials for Paint.NET and for GIMP (http://www.wikihow.com/Recolor-Anything-on-Gimp) Essentially I do the following: Add a new layer Use lasso to select the waistcoat Use bucket fill with the purple colour Select multiply for the layer. This gives me the result I am looking for, but only in the region that I have selected. Not surprising really, but something that I can't get right and that seems to be skipped over in all the tutorials is: how do I select the area correctly? Unless I go down to a really high zoom and spend ages with the selection, I end up either not selecting everything or I end up with leakage into other parts of the clothes. This tutorial (http://www.recolored.com/tutorial_quickstart.php) for a paid for product seems to let you just roughly choose your selection then it uses some algorithm for edge detection to make the correct selection. Is there anything in Paint.Net to help me choose the selection like this? I have tried the magic wand, but the since the picture is greyscale, it chooses random selections all over the image instead of just the waistcoat.
