Help with colour!

[AmyNina]

Hi guys, I recently let one of my Buffs hatch some eggs. Well only 1 out of 3 made it, and I'm trying to figure out the colour!

Firstly, the dad is 100% Buff
The mum is either Buff, Black or Splash.

I think I can rule out the Buffs, as all my Buffs are true to their colour so they would breed Buff babies.

Does anyone know what

Buff x Splash
Or
Buff x Black

Would make?

The chick kinda looks either blue or Lavendar almost (I know that's probably not it, just what it looks like)

If anyone can give me any ideas, much appreciated!

That chick looks like recessive white, actually! Both the parents must have been carrying the gene!
