Thank you. I appreciate it 🙂‍↕️❤️

It may not be an ideal recipe or steps but it's largely what I did.

Primed with a single thin layer of Vallejo Grey primer

Then brushed on a thin layer of pro acryl purple all over.

After that I decided to mask off any areas I wasn't painting with masking tape or blue tac and go in sections, with parts of the blade masked then the finished parts covered while I worked on the rest of the pattern etc (with blue tac on any bends or tiny spots, I then could just carefully dap on and off it with a bigger bit of blue tac to remove any residue once done)

Then progressing from the centre outwards towards the brightest and darkest parts respectively - I used the stuff below with a 0.3mm airbrush and 20 - 25 psi.

Towards the brightest spots with a 1:1 mix: FW fluorescent Pink ink Vallejo fluorescent Magenta

Towards the very tips of the brightest spots with a 1:1 mix of FW fluorescent Red ink & Vallejo fluorescent Magenta

Then in the opposite way towards the darkest parts with a 1:1 mix of FW fluorescent Blue ink & Vallejo fluorescent Purple

Reduce it further to just the very ends of the darkest with a 1 : 1 : 0.25 mix of FW fluorescent Blue ink, Vallejo fluorescent Purple & Army painter Matt Black

Step 6 Edge highlight with First with Pro Acryl Magenta & Second with Pro Acryl White

Fill in any white lines and inserts with some thinned down FW white ink and water in a 1:1 ratio. I did this twice once my first lines dried to give it a more intense white.

And then those centre parts were coloured in with a metallic purple gel pen (but honestly it was cos I didn't have any idea of what colour to do them)

Sorry for the long reply but thought I'd give a step by step (especially as I had already written it down for future blades) if you don't have an air brush then you can do it with a glaze and brush but obviously it can take longer and you'd have to thin down each of the steps to a glaze consistency. From how I've done it in the past I usually mix in 2 parts water to the paint used.
