How to get the selective color effect

When I started thinking about this Codebrawl, I had essentially two ideas how to do get the selective color effect: Try to detect each crayon as an object and keep one of them in color, or take a reference color and just keep the colors that are similar to it. The first idea would be more universal, but seems to me much harder to implement. I chose the second one, so I needed a way to measure the distance between to colors.

How to measure the distance between colors

There are several ways to get a value that tells you how much colors are like each other. If you have an RGB pixel, you could just take these 3 values as coordinates in a 3D space and calculate the distance there. I did not actually implement this, as it does not represent similar colors in the way we would see them. For example, the color (255,0,0) and (127,0,0) would both be just red, but they would have the same distance as (255, 128, 0), which introduces green to the color mix and looks pretty diff

	If you want to clone an svn repository with git-svn but don't want it to push all the existing branches, here's what you should do.

	* Clone with git-svn using the -T parameter to define your trunk path inside the svnrepo, at the same time instructing it to clone only the trunk:

	git svn clone -T trunk http://example.com/PROJECT

	* If instead of cloning trunk you just want to clone a certain branch, do the same thing but change the path given to -T:

	git svn clone -T branches/somefeature http://example.com/PROJECT
