Its hard to see from their bottles what is what.
This article kind of describes them

Hi everyone Im a newbie on here - I have just joined the "RGM Uk Site" and ordered "I'll be honoured" (a caramel colour) - the offer they had was just too tempting.... I normally use gelish and like the product very much - hoping that RGM will be as good, you all seem to give it a "thumbs up" Ive looked at FK's database to see if there is a similar colour in the gelish but couldn't find this RGM one listed. Does anyone know what the dupe colour would be?????
Have been tapping thru your fantastic website over the past two weeks and still have much to read............................. thanks in advance for your help.
