Abraham Kierszbaum & Laura Tres, “Histology & Cell Biology”, 5th edn, 2019 was the topic of an earlier blog post.

INTRODUCTION.
Oliver Sacks, “The Island of the Colorblind”, 1997 was a book Achromatopsia on the Micronesian isle of Pingelap. Achromatopsia (ACHM: colorblindness) is a hereditary condition.
Complete Achromatopsia is characterized by a total absence of color vision. People with complete achromatopsia (ACHM) cannot perceive any colors; they see only black, white, and shades of gray.

COMMENTS.
ATOP this blog post is a test for “colorblindness” achromatopsia. You are asked what number values are inside the circular disc ABOVE.
The correct response is: 7 13 16 8 12 9.
The retina of eyes has “rod” and “cone” photo-receptor cells. These are four (4) of the seventeen (17) “transducer” cells listed BELOW. At the BOTTOM are the other histologic groups of cells besides “transducer” cells.
The human body is 211 cell types. The cell groups here are used in images:
LPGNAWZQVBUCKSMTEIXH.
Tb is “eye cone-blue photoreceptor cell”.
Tg is “eye cone-green photoreceptor cell”.
Tr is “eye cone-red photoreceptor cell”.
Oliver Sacks, “Island of the Colorblind”, 1997 is written to give its readers the “view” of the medical condition suffers.
