I'm the owner of white painted Solaris, which is in the combination with Black-on-White LCDs looked good to me. However, I have to admit, the choice for five 40*2 LCD itself was not ideal to me. The surface is huge, so, every LCD you see from different angle. For me personally it was hard to read the value from side LCDs without changing the position especially if it has a fleck. So, instead of complaining, I came to the idea to replace them. I chose White-on-Black. I used that combination before at my other projects and haven't expected any troubles. I'd prefer Noritake VFD displays instead of LCD, but replacing five 40*2 would result in much higher costs. So, I stopped at LCD, by some Chinese vendor at $25 each. The replacement looked to be straight forward, unfortunately, with some difficulties. There is no contrast tuning fro each LCD in the Solaris, and since I install inverted type of LCD, it needed different contrast voltage settings. In order to do that I needed to desolder original contrast smd resistor (one for each LCD) and solder another one. But I didn't want to do that. So, instead, I disconnected contrast pin on LCD side and soldered 1k resistor to the ground.
I attached some photos. See the comparison with original LCD - view angle is much higher now. LCD is well readable even with flecks.
