As for "similar color", the dply logo appears to be black. There is some blue (not the same blue) on the page, I guess?
Every link on the page is blue, as well as hovering (which is why I said their 'brand' color not their logo color)

So, two websites, using the same font for their logo, and both using some shade of blue somewhere on the page?
