Like that famous dress that changes colour depending on how you look at it, so is Rassilon.
2 photos taken while we watched the cricket shows the relationship between light and colour.
In the first photo Rassilon is a greyhound. His head and face are grey, but his back is showing the fawn brindle.
In the second photo, taken less than a minute later, but at a different angle shows Rassilon to be brown.
The light in the bedroom was exactly the same for the 2 photos, only the angle changed. Rassi was still beautiful. We went to check the mail again and there were more people out, and quite a few had to come and pat Rassi, but he left the adults when the kids came to him.
