These are the recognized colors that silkies come in:
Bearded/Non-bearded White, Bearded/Non-bearded Black, Bearded/Non-bearded Buff, Bearded/Non-bearded Blue, Bearded/Non-bearded Splash, Bearded/Non-bearded Gray, Bearded/Non-bearded Partridge, Bearded Self Blue,
Bearded White Naked Neck,
Bearded Paint.
Then of course there are all the lovely mixed colors and project colors that people have which in my mind are often more beautiful.

Look up for example calico silkie and you will see what I mean.
In order to maintain the above colors, silkies have to be kept in "color pens", which most people do not unless they are serious breeders. Many people who want to breed silkies (and many other breeds for that matter) start with BBS (blue/black/splash) as these colors can all be kept together and still breed "true".
I agree yours is not paint and likely splash. Paint is crisp white with patches of black and is the result of dominant white (most silkies are recessive white) over black.
They are crisp white with clear black patches. They have their "spots" at hatch and they develp more as they grow.

Splash is part of blue genetics (BBS) and is a light grey (blue) with darker grey (blue) "splashes" coming through. These birds are usually hatched a light silvery white and the coloring comes in as they feather out.

Lavender (officially known as selfblue) is a dilute of black in the same way that blue is, but is completely different genetically. You need to have two lavenders or a bird that is recessive for lavender to create lavender chicks. Your bird could very well be. There should be no flex or anything and she should be a very even light silvery color. Some blue birds can appear to be lavender as well, the blue has more of a gradient of color and it’s not completely uniform like lavender.

Hope all this makes sense! I am by no means an expert in genetics and I’m still learning, I find the topic very fascinating!
