It is totally clear that this tool will help developers with something realted with colours..., for sure!!. Do you need to choose a color from a palette??, do you need to copy a color from any other place in any homepage??, do you need a Color Picker similar to ones that can be found in Photoshop and Paint Shop Pro???. All this and more can be found within this handy tool.
It also allows to zoom into a homepage by 1000%!!. Strange tool but not if you want some colours in a picture!!, ..isn't it??. :)
It even analyzes all the colour in the DOM of the homepage!!. what else??
