I love working on new colourways, though it isn't something I do all the time. Especially when it comes to repeatable colourways. Often when I dye for the sake of dyeing or myself I just throw colours together to see what madness comes out of it. This part of my process is very haphazard, but often informs my more structured dyeing. I like to play with colour to see how they combine in a more real way than on a colour palette.
When designing a new colourway I usually have been prompted to think about a Fandom or theme and then I tend to select the first few things that come to mind to take down the research rabbit hole.
So for example when working on the Phat Fiber samples for January with the Theme 'Dragons and Fantasy'. I had originally been thinking about fiery reds browns, colours I don't dye often, but are commonly associated with Dragons and their fire breathing ways. However when it came to dyeing my samples I was suddenly reminded of Eragon by Christopher Paolini and thought it would be nice to play off other colours, so I was guided to his dragon in particular Saphira.
