If the snakes has this shading as a baby it will also have it as an adult. Mojo BELs & Mojos crossed with other het for BEL morphs will have shading on the head- this can be grayish to lavender in hue & opaque to opalescent in saturation. Especially nice is the Hypo-Mojo-Lesser as the effect is subtle & wow at the same time. I personally do not care for the solid white Blue Eyed Lucys, but if you do the Lesser X Lesser or Lesser X Butter does produce them.
