the example could be seen from the new google calendar
it was white font
on a saturated color box (colorful, very 'rich' in colors', 'bright', or im not sure what's the technical way of describing this)
what are the benefits and harms of this because it appear to be very very hard to see the font when this is done
p.s. hello this is not duplicate cos 'bright' colors arent dark, and also there's no answer to google calendar, so it shoulnt be 'duplicate'
