Bleaching
 

Can anyone tell my why my color is yellow when I bleach my cardstock instead of white?

It depends on the color of cardstock you are stamping onto as well as the brand of CS. Sometimes when I stamp on blues, it will turn purple, other times light blue.

It all depends on the core color of the cardstock, which can vary from dye lot to dye lot - for example, I was once making 50 cards using Mellow Moss and bleaching, half the cs bleached to white, and when I opened a new package of MM it bleached to a color similiar to Barely Banana.
The core colors can vary with each lot because of the mixture of paper they use varies with each batch.

I hope this makes sense,
