The first section on the left side of the page has a list of 123 tropical colours in different shades of orange, grey, and brown. The colors are arranged in a grid-like pattern, with each color representing a different shade of color. The shades range from light to dark, with some shades being shades of brown, orange, and gray.

On the right side, there is a section titled "RLM 78 (1942)". Below the title, there are two smaller sections titled "After the retreat from North Africa, the tropical colours were the same color as the rest of the world. After the retreat, the colors were a mix of different shades, including shades of gray, brown, and beige. The text on the page explains that the colors are from the early 20th century and that they were used in the early 30th century. The page also mentions that the book was published in the United States and that the color scheme was created in 1942 and 1943.
