Harlequin Rasbora colouration change / smudge

One of my Rasboras has developed a grey/black coloration on its head and all the way along its top like a stripe.

I've had the fish for 10 months and this is the only one with these markings, and they've only just developed in the last few days.

Water parameters are fine. Behaviours seem normal; the fish is eating fine, swimming fine etc.

The only changes in the tank lately are food related, I bought a few new types for variety.

EDIT: I tried to attach a picture but this is a new account and I don't think I can post links.

I'm not sure if this is something disease related or just a normal pigmentation thing?
If its normal, why did it only just happen now after all this time?
If its not normal, can anyone help diagnose it and/or suggest treatment?

Thanks for your time.
