You do mean crisco shortening don't you not cooking oil?

i use crisco shortening not oil sorry

Try using oil-based colouring, like you would for colouring chocolate.

or powdered colors.

I used a crisco based bc for the last cake I did and had no problems getting vibrant colors. I use Americolor gels.

I used to have that problem with the Wilton recipe that was half butter and half crisco. I use Indydebi's recipe now that's all crisco and adds dream whip powder, and it takes color better. I never get that spotty look that it used to develop.

Is your icing thin when you start coloring it?

Vibrant colors often take more colors than lighter colors and I have found if my icing is already soft or thin to start with then when I add a lot of color gel to it, it tends to separate the color/liquid from the crisco. If I am making black or red I usually add in more powder sugar or corn starch to the icing to help balance the amount of colors I use.

I have that problem with one of my buttercreams because it doesn't have enough powdered sugar in it to hold a lot of food coloring- try adding more sugar.
