What is the use of the first の in this sentence?


"色 **の** 薄いものと濃いものを両方使うときれいに見えます。" I thought this was the case where の
substitutes が but this is not a relative clause. I'd just like to know about
this particular use of の.




As Leebo has mentioned, this is a relative clause. In other words,

> 色 **の** 薄いものと濃いものを両方使うときれいに見えます。

and

> 色 **が** 薄いものと濃いものを両方使うときれいに見えます。

pretty much mean the same thing.
[This](https://japanese.stackexchange.com/q/12825/29327) is a good explanation
of が and の usage.
