Coloro is an awesome app to add colour creativity in designs. There are specific tools are available in market to enhance the performance of your CSS code with perfect gradient. I have found some similar graphic tools such as Colrd, Color Explorer, Designspiration, and TinEye. These great colour tools will find you the accurate shades for the graphics.
Its a nice tool, but it isnt accurate, it depends on your camera. It`s the same as taking a picture and then getting the color code from that photo. But interesting nevertheless 
adobe kuler is much better and very professional, thanks for sharing an alternative.
