I've been extreme multi-tasking lately and have managed to do a couple of new tutorials while simultaneously making up some samples for a demonstration, so without further ado, here's how I colour black hair...
As usual I have stamped the image ( Sitting Gorjuss Girl from Sugar Nellie ) with Memento Tuxedo Black ink, and this time I've used smooth notebook card from The Papeterie.
The first colour I use is black, using light feathery strokes, I've coloured quite a large area of the hair (more than I would usually colour for any other hair colour. I've left enough white areas, where I imagine the light would be hitting, for blending.
Next up, I again use feathery strokes over the black areas and slightly into the white areas, this blends the 2 colours a little - don't worry about the blending being seamless yet.
I repeat this process with IG3, moving a little further into the white areas - but leaving a little white visible as a highlight.
By colouring over the Black and IG5 areas with the IG3 you will notice that there is a bit of bleaching - to counteract this and also to give the hair a glossier looking finish I use Indigo Blue over the darkest areas, using very light feathery strokes.
I then used Powder Blue over the whole hair area using very light feathery strokes, this blends all the colouring without bleaching out too much of the depth of colour.
If necessary you can touch up the black a little...
And this is the finished image...
thanks for looking and hope this was helpful.
