This looks more like icy cavern because of the white filter but I like it anyway, it fit the purpose of my water temple
Oh god I need to rework all of my project's map now
It probably does look similar, but if you look more closely, the ice cavern tileset is more cyan in color, while mine is a more HD periwinkle. Here's the side-by-side comparison:
Another reason the color scheme is darker than the ice cavern tileset is that in the video, this was the color your temple tileset appeared to me. My eyesight is a bit unique in that, while I am not colorblind, some colors appear slightly different to me in terms of vividness versus dullness. I can still easily distinguish one color from the next, but for example, a shade of bright purple (magenta) sppears more bluish than pink to me. Plus, I wear blue-tinted classes (to help block out UV rays).
I also have a bunch of semi-transparent tiles that can all be used to give the whole atmosphere a "deep undersea" vibe to it if you want. Plus I think it helps the tileset stand out more
I am glad that you still like it nevertheless <3
