I got them both back in mid April 2016 at 1/4". They are both male and are both around the 1.5" mark. They started showing their colour at around 1", but they still get really grey as they get farther away from moulting. This little dude moulted about three weeks ago and that is why he is still looking so black. His brother is looking a lot greyer.
@VanessaS@The Grym Reaper When I got mine in November 2017 it showed a hint of red and overall more grey-ish, now it's more like a bown-ish grey. So, I hope it's finally getting into premolt and is gonna moult in the next month(s). We'll see how it looks then. Thanks for the info!
