Incorrect license information

[brauliohms]

Dear Antoine Grondin, your LICENSE file, it says that :
"> Except for functions HSLtoRGB and RGBtoHSL, under a BSD 2 clause license:"
but the text describing the license refers to the BSD 3 Clause license.

So I would like to know which is the valid license BSD 2 Clause or BSD 3 Clause?
