https://drafts.fxtf.org/filter-effects/#FilterProperty brightness() = brightness( <number-percentage> ) Negative values are not allowed. However, WebKit and Blink currently accept negative values. https://jsfiddle.net/ericwilligers/y4j8hzvs/ Corresponding Blink bug: https://bugs.chromium.org/p/chromium/issues/detail?id=776208
