The problems of matching colours

I did the necessary work on the broken Victorian panel (see Feb 2016 post) recently. The glass we had ordered was indeed a close - but not perfect - match, the three replaced lights can be readily identified in the photos I took on my phone (which perhaps bring out the difference more than is apparent when actually looking at the panel).

Closer examination of the glass in question did lead me to wonder whether it was the same as the glass I had removed, or the matching pieces at the other end of the panel.

I have left the customer a piece of the yellow glass I used, just in case she wants to replace the bottom left light; however, when reviewing the photos I took in February, I noticed that that piece was slightly darker than those I had replaced anyway.

The glass will, of course, weather a little, and I was not able to polish the panel aggressively while the cement was still soft; once it has hardened some Mr Sheen and an old pair of tights will work wonders. I will still notice the difference in colours, but possibly others won't!
