# What does the fading selection color mean?

In the picture you can see that the last vertex selected on the edge loop is somewhat separated by a color change from the rest of the selection. What does this mean?

• The fade from orange to black along an edge means that the edge in question is connected to the selected vertex, even if the edge itself is not selected. The situation in your screenshot is caused by two vertices in the same place. These are called doubles and can be automatically merged via W > Specials > Remove Doubles. – gandalf3 Dec 15 '15 at 7:19
