Dark colours. How do people recreate these? Obviously you cant project the colour ‘black’ with light but is there any way to improve an LED response to ‘darker’ colours at all? I was thinking some kind of grey diffuser perhaps?
I could barely see the dark purple color on one of my projects with just a single 60 watt bulb turned on in the room. When I put the same project under solar screen (grey 80% light transfer) the color was much richer and visible but a bit changed by the grey. I would think you could also use a raised divider between pixels to keep brighter pixels from washing out the darker colors.
Interesting. Thanks
