The plant that is usually called hair grass is a spikerush.  The leaves
are hair-like; round in section and usually straight.  The small E.
tenellus has downward curved, flattened leaves with a vein down the
middle. The reddish color can be a streak down the middle, or it can take
the whole leaf.  In my tanks the small E. tenellus doesn't need to have
real bright light to show the red color.  It doesn't turn fully green
unless it is heavily shaded.

It sounds like what you have might be the small E. tenellus, not what is
usually called hair grass.
