In the actual SVG it does, exactly what we send them is what they print aside from positioning. However I'd like to see the rainbow go as close to the edge of the printable area as possible, so if you want to run the rainbow on the two other keys up to the edge that works for me too. There's a lot of controversy over how dark the blue from /KL's gb is, but its a medium blue and a darker purple would provide decent contrast with it, but the darker colors aren't going to show up very well regardless since it's on blue and not white... so expect that purple isn't going to be very visible regardless.
Hazeluff, whenever you've got SVGs you're good with me sending into Melissa for her to give the thumbs up/down go ahead and send them to me in an email. You should still have my email from the other gbs but if you don't lmk and I'll PM it to you.
