Difficult to see cells using the bulb theme

I usually run on lowest lighting on my phone to conserve power, and for the most part it's not an issue, but the bulb theme's cell grid is practically invisible at that lighting.

What would you suggest? A different colour palette or modifying the shape? I wanted to keep #39 unmodified because the story was nice, but in the name of accessibility, we can change it if we should.

I would suggest making just the cell grid more visible, the palette can stay as it is.

I think it is okay to apply a little alpha to the colors of the bulbs, as long as the effect of glowing in the dark remains.
I myself find it difficult to play but I consider this a challenge that belongs to that theme and there are other themes to play, too.
