Sunflower seeds

Why would one of my yellow sunflowers be producing different colour seeds?
One looks to have pink seeds and another has black and pink seeds?

Perhaps not all of them are ripe yet ?

I had 1 sundlower 3 years ago and each year have planted seeds and then collected them etc
They have always been white! Lol
Will keep an eye on them
