You can only get this effect in the center of your visual field due to the organization of your retina where you have color vision. The rest of your eye is much more sensitive to light so you can see dim stars more easily in your periphery by looking away from them a bit. Maybe you can use your own biology to help enjoy the night sky even more! If you get a friend, you can use colored pen caps and get them to hold them in your periphery and tell them what color it is. You don’t be able to until they reach the color vision part of your visual field if you stay looking forward.
It’s trippy, but your brain fills in color for you a lot of the time.
I prefer smart wool, but am totally on board with nice merino wool socks from any brand. Happy feet have helped me maintain a happy life. It’s like a good pillow or the right jacket for today’s weather for me.
Totally agree on the boardgame suggestion if it suits their personality. You need to know what complexity they are into, first.
