Apart from the fact that a color ereader would be (obviously) capable to display black and white text in... well, black and white...
There are:
- picture books
- comics and mangas
- some books where color was a precise stylistic choice
I'm thinking for example to Ende's Neverending Story, whose my copy was entirely printed in red and cyan depending on who the author was writing about, but I'm sure one can come with many more
- some books where the illustration art was impressive and not just decoration
Can't name any right now, but you know there are a few
- manuals
Do-it-yourself, for example, or to name a few I have several texas hold'em books, both in print and in ebook, where color definitely improves the readability and... well I don't think I need to name more manuals that benefits from colors, do I?
- Academic books
It is a long time dream for governments to give ereaders to the students for them to substitute the heavy books they have to carry on shoulders (well maybe not in the States, but here for sure), and they
need colors
- Books about photography
Unless it's b&w photography
- Some scientific book
I recently read "Our mathematical Universe" from Max Tegmark and it was a PIA looking at all that pictures in the book in grayscale. No, seriously.
Those are the first categories that come to my mind, but I'm sure there are more.
As you can see, they are not so few, and the fact you (generally speaking, I don't mean the original poster specifically) are not interested in them doesn't mean they do not exist and they wouldn't benefit from a color e-reader.
So yes: there would be (plenty) of use for color e-readers. It's just that it doesn't make to a critical mass for it to be economically convenient to develop an ereader for such uses... or the other way around, an ereader with the needed features (i.e. color) would be too expensive right now to be used to read that books.
For now, at least.

Besides we already have color readers, We call them Tablets, I-Pads and Slate computers. Why would we need to add anything more to that line up.

Because those are not readers; or we would use them also for black&white texts. Why would we add e-ink readers to the lineup. Because they are less fatiguing for the eyes, less energy-hungry, etc. etc. the whole lot. So would be a color e-reader compared to the lineup you quoted. If it existed. Unfortunately, every prototype made so far had a quality such inferior that any other possible advantage was irrelevant. But that does not change the principle.
