I mentioned this at some point on the Steam forums.
I have some vision issues, and at times the white/yellow circles can become indistinguishable from each other. Especially in Autumn, when everything turns yellow, or Winter when the ground turns white.
Others have suggested a pointer line or arrow, or a “jump to” function, which sound okay, but would require a lot more changes to code.
I suggest a simple change in color- change the yellow color to a bright high contrast color similar to how houses are outlined in bright green or bright red. A change of the color code assigned to the object- something that will not blend in to the landscape. Bright purple, Bright blue (like fishing spots), bright green or bright red. I think I had sugested bright orange, but in Autumn, if you have a lot of Maples and Oaks, that might blend and disappear. I lean more towards bright blue or bright purple, since (without desirability or water filters on), neither of those appear in the landscape naturally. This could, IMHO, really help everyone, but especially players with older eyes (don’t make me take of my bifocals and shake them at you…), vision issues, and certain forms of colorblindness.
