When only the outline is shown, this is sometimes called a white Cross although this is a misnomer. A more accurate name is Voided Cross. This is a heraldic term for when only the edge of the cross is traced. Where the cross is ‘filled in’ it is usually shown as a Black Cross, unless some other color is significant. The Voided Cross is also sometimes referred to as a Fimbriated Cross. Fimbriated means fringed.
