Tiles with light blue showing white on Laptop

Recommended Posts

I've found a problem with colors on my laptop... For whatever reason when loading my map editor, I find the snow and ice tiles 'blank', or simply just white.

Is there a reason this is occurring on my laptop? My iPhone and Desktop Computer show the two tiles perfectly.

They should like look this picture:

You can't even see light blue or anything, it's just white. Yet all the other tiles, and objects look fine.

On my desktop LCD monitor, I can barely see the blue in your second picture. I have to stand up from my chair to do it, so that I kind of look down on the monitor from above. Probably just a weakness of certain LCD monitors. Maybe try upping the contrast just a little bit, so that the blue isn't so close to white?

Many cheap LCD's don't actually support 24-bit colour and convert the input signal to something lesser, like 18-bit colour ([i]64 colours per channel / 262144 colours total, instead of 256 colours per channel / 16 million colours total[/i]). I'm guessing your laptop has a cheap-and-nasty monitor, so light-blue is being quantized/"rounded-up" to white.

Looks like I'm going to have to adjust my color pallet... Man this isn't going to be fun. I use a top of the line monitor, and even my iPhone displays the images correctly.

Since it's for a classic game, I could just put the pallet to High color (15/16-bit). This should fix the issue for older monitors.

I did a ton of tests and cannot get a better way of using colors that will work on all monitors... I saved the pictures to 16bit, which didn't look much different on my monitors. I looked on the laptop again, it's displaying 32 true color, and if I open the screen more wide it shows the blue. I'm guessing the only thing I could do is just use color pallets for 16 bit to be sure, but again the color at 16 bit isn't showing anything different regardless of conversion, other than darker grass...

What can I do...?

New one works fine on the laptop.
