+## Day/Night system FAQ

+### Q: How do I mark certain colors in a palette as light-blended?
+A: Create a `.pla` file in the same folder as the `.pal` with the same name.
+
+In this file you can enter color indices [0,15]
+on separate lines to mark those colors as being light-blended, i.e:
+
+`06.pla:`
+```
+# A comment
+0 # if color 0 is listed, uses it to blend with instead of the default!
+1
+9
+10
+```
