Named for lightning
An older version of Wikipedia's lavender article listed #F4BBFF as brilliant lavender. It gave a second name too, electric lavender. The idea was that lightning usually looks electric blue, but in some weather it can look like this pale purple pink. The only source cited was a website, so the name has no long history. The same code has its own page here as electric lavender.
Pinker than CSS lavender
#F4BBFF is much pinker than the CSS lavender, #E6E6FA, which is almost white. It sits closer to mauve, #E0B0FF. Use dark text on it, since white text only gets 1.57 to 1.
