Hellion Gang scheme

So I'm planning on starting a Hellion Gang after I get a bunch of other models done for people, and I was wondering if my paint scheme sounds alright.

I'm wanting to go with something bright and vibrant so I was thinking of priming the models grey, then spray painting the skyboards with a coat of Evil Suns Scarlet. The models themselves would get spray painted with Flash Gitz Yellow.
Afterwards I'm going to try painting some orange runes on the skyboards and painting the engine with a metallic colour that has not been chosen yet.
The Hellion riders will get metallic colours added to their weaponry as well.
Then I'll go over any visible skin of the riders with dheneb stone followed by a wash of nuln black.
Afterwards I'll highlight the skyboard's red areas with a 1-1 mix of Evil Suns Scarlet and Ceramite White and then on the orange areas a 1-1 mix of what ever orange I choose and Ceramite White.
The actual riders will be getting a 1-1 mix of Flash Gitz Yellow and Ceramite White where I see the highlights needed, and then the centre of the highlights will be have a bit more Ceramite White added. (2-1 on Ceramite White and Flash Gitz Yellow instead of 1-1)

I'm not sure if I covered everything but how does it sound? *The bases will probably be rocky/mossy and the hair will probably be some form of bright orange.

Grey and red? Looks like my paint scheme...
Something like this:

Another idea is a light blue and white. Although It's a tough choice for me, so I'm testing out each one on two different Kabalites. Afterwards I'll probably post the pictures of them on here to see which one is liked more.
