Cycletrack bird - not quite as black (yellow) and white

Had a wander along the cycletrack this morning - the bird I believe my brother-in-law saw was a what appears to be a washed-out Great Tit, very pale yellow, pale grey and brown, it was pretty much south of the grid ref where the path zig-zags upwards by a derelict farm building. A few redwings and greenfinches - not birds I'd seen much of this winter.
A search on the web showed a nice picture of a similar very pale Great Tit at Portland
