"Just flipping the gradient direction is the equivalent of the environment light changing direction when you hover over/click a button, this makes zero sense."
Inverting the gradient for pressed down button can also be seen as a convex surface becoming concave; think a membrane button. (A flat button wouldn't have such a gradient.)
While that kind of "faux membrane" buttons are not very common in real world, the inverted gradient effect immediately gives me feeling of "popped in" button. Am I alone here?
- chrisdroukas 15y agoThat makes more sense if the gradient is radial. For a linear gradient, inversion gives the appearance of a changing light source - just like the example given shows. A radial gradient, on the other hand, might more typically assume an 'oveerhead' light, which is why inversion makes sense.
- Yaggo 15y agoFor me the linear gradient hints that the surface is curved on one axis, i.e. is cylindrical, not spherical. Of course the context plays a role too on the perceived illusion; the appearance of changing light source may be stronger for lonely button (vs. group of elements sharing the same light source).
