Thank you to everyone for the info on the colours, especially to Caz, who had the full explanation.
I had very, very, very vague memories of an art class way back when as she described it :-)
That triggered some old memories :-)
And it would seem that the majority of the comments sided with hubby about the colour.
General census is gray
But I am adamant it is brownish in tinge

Have a wonderful weekend
