I don't remember the running rigging line being in four different colors. I know the standing rigging and running rigging lines is a different color. I didn't care for the line that came with the kit I purchased dark brown for the standing, and natural for the running!!
Also, just a heads up, there are some construction issues with this kit. If you are not aware you might want to check some of the builds, already completed. You will need to know about them before you get into building the kit. nothing heart-stopping but need to know.
