Harp strings are color coded so that the player can identify what strings to pluck. The C strings are red and the F strings are black, arranged in octaves like a piano.
There is many good makes but in my opinion it is dunlop it has a black sticky rubber grip is placed on one side of the wood and a red spotty lumpy grip on the other side and some times in different colours. But there is another great make called butterfly and killer spin they are a bit similar but are really good to hold and to play with.
they use a guitar with strings as opposed to a guitar without a strings and it is red
