Yellow is the color of the tennis ball

week 28 (UP Medicine Tennis Court)

What color is a tennis ball? My answer is yellow. I learned recently that this is quite a divisive question.

The seemingly trivial question tore apart our usually congenial group. Lines were quickly and fiercely drawn, team green against team yellow, as my colleagues debated the very definition of color itself. Swords were brandished in the form of links to HTML color codes or the paint selection at Sherwin-Williams. Attempts to broker a cease-fire, to consider that maybe tennis balls are actually yellow-green—or green-yellow, or chartreuse—were brushed aside. At one point, I lashed out at a colleague who then reminded me we were on the same side.

The article offers a theory on color perception.

When we’re looking at a given object in different types of light, our brains make substantial color corrections that allow us to see the object in a stable color over most lighting conditions. Conway’s theory is that some people discount cool colors in their perception, while others discount warm colors, in order to view objects consistently as the light changes around them.

It goes even further: one's perception of the tennis ball color may shed light into one's lifestyle.

In my second year of residency in IM (sometime in mid-2016), I enrolled in a tennis class. The court was a few steps away from my dorm room. Never mind that the interns saw me sweat it all out.  Weng, my young instructor, said at one point that I had a good backhand. The last I heard about Weng was that he got married and moved to the province.

Tarps and COVID-19

Saw this in my feed. So Pinoy in many respects:  the graduation photo the tarp with three fonts: Monotype Corsiva ("Congratulations"), Arial (the girl's name), and the serif below the papaya tree the use of the middle name the color scheme (pink in white) the iconic Philippine countryside It's the first time I'm hearing about Zarraga, some 16 km north of Iloilo City. Seems like a charming place to visit. Also COVID-free. 

Week 9, 2012: Aboard the MV Logos Hope

I met old friends from college last Saturday. We had breakfast at an old restaurant along Ongpin Street called Saludo's. Some of us went to Logos Hope, a ship with lots of books inside it—some 5000 titles, we were told. The sun was hot, in a cancerous, melanoma-inducing kind of way. Summer is just right around the corner. Took us a while to get inside the ship. I thought this view of Manila's skyline from one of the windows was amazing. We saw what we came for: books. They were sold in "units" that had a corresponding peso conversion. The books sold cheaply, so I got David Copperfield by Charles Dickens for 150 units (Php 150). I plan to read at least one Dickens novel this year, 2012 being his 200th birthday. (I'm ashamed to admit I haven't read a single novel of his, ever). I saw Nancy Drew, Hardy Boys, classics, modern fiction, modern Christian literature, biographies, medical and nursing textbooks, and children's books. Visit
