Adding a light and colour palette feature on each assets

it would be great if we could apply a customizable light effect or even colour on assets, be it items or even tiles…. ideally with a transparency slider.
This would allow to mark down trapped tiles and magic items.
It would also be an easy way to change the colour of an otherwise standard item: you apply a grey semi transparent layer to a piece of furniture, and now the light wood coloured table has a different tint, the marble altar suddenly has an onyx colour and is dedicated to a dark god.. you apply a red hue to a floor tile, or even a red light effect, and it stands out as trapped but you can still see the floor tile underneath it… you apply a white/blue shine to a statue, and suddenly it's made of ice or crystal but, mechanically, it's still the same item. Next to adding infinite assets, you multiply the value of each asset and its versatility.
