Light & dark transparency grid

[Pascal P]

Hello,
when previewing alpha picture, we can choose color of the transparent grid, it's great, but working with different assets could be better again.
For an example, here are 2 different assets :

Lock.png

Rock.png

One of them is light (so for a good preview, I prefer a dark grid) and the other is dark (here, a light grid is better).
Of course, I could use a middle gray color to preview it right, bug gray assets may not be visible.

So, here is my wish :
configure 2 sets of color for a dark and light grid which would be automatically choosed if the average of luminosity of the picture is light or dark.

If autodetection is too complicated, we could have a button to switch grids like this (if you need, psd file is in attachments) :
