A scent, not a crayon color
In 1997 Binney & Smith, the company behind Crayola, sold Color 'n Smell crayons. Each one had a scent with its own name, but the wax used regular Crayola colors. Bubble Bath was the scent of the tickle me pink crayon, which Wikipedia shows as #FC80A5. The other scents are in the Crayola crayon list on Wikipedia.
The code on this page, #E8E0E9, is not that pink at all. It is a very pale lilac gray from an open online name list, with no known source. It sits close to lavender blush.
