It does look a bit peaky - as well as the red tinge the green is a bit pale.
I've known this happen to ivy when the plant is under stress - perhaps it
was overdue for re-potting and the nutrition in the old compost had been exhausted?
And while ivy doesn't like being too wet, it does object to being over dry.
Now it's been repotted in fresh compost, and with regular watering so that it doesn't dry out, hopefully it'll soon be a much fresher green.
