  * These are the color codes for the lo-res colors that are available.
- * Each pixel in lo-res indicates one color. These are colors I found
- * somewhere online -- I'm not sure if they are exact matches, and are
- * subject to change.
+ * Each byte in lo-res represents two visual cells, each 4 bytes high,
+ * which are indicated by considering the low and high 4 bits separately
+ * and matching them against the colors in the table below.
+ *
+ * These color values are the "NTSC Corrected" colors as defined in the
+ * Apple II Forever Anthology, v0.3, Hires reference (pulled from
+ * archive.org).
