I started with a base of Barry M Pearl, the off-white one from the Silks range. I then dotted away with a whole host of other Barry Ms, mostly Gelly colours.
I'm not particularly happy with the way each colour blends into the next (i.e. they don't!) but I do really like the ring finger because the colour change seems a bit more natural.
I think the main difference between the original design by Jema, and mine, is that she has a lot more colour coverage on the nails - I was perhaps too cautious and left too much white showing. Plus I needed a better blend of colours too, so that it's not a sudden switch from one colour to the next.
I did get a bit bogged down in the idea that the colours needed to be in proper rainbow order, but maybe I should have given up on that and just done a more gradient-like blend.
Having said all that, I'm comparing mine to the original, which is a bit negative, I know. So without the comparison, I really like these nails, so much so that I've done them on my right hand and will wear them to work tomorrow.
