Vibrant Visuals - Problems with Signs and Colored Lighting suggestion

I've been testing out vibrant visuals in my city, were road signs are crucial for simple transportation and noticed that with the vibrant visuals I have to basically be standing a block away from a sign to actually read it. I hope that signs will be visible from farther away once Vibrant visuals officially release.

Also, I add glowing inc sacks and white dye to my signs to make them easier to read, but that has been entirely done away with in the preview of vibrant visuals. I hope this will not be the case in the future.

Also, now that Mojang is looking into the game's lighting, could different colored lights be a possibility in the future? I feel like the ability to choose between lighting would be benefitial as at the moment all light is a warm beigeish.
