I had a discussion about colour blindness and how the light receptors in our eyes can distinguish between three colours: red, green, and blue. (For some women known as 'Tetrachromats', they can also see red-green.) I couldn't remember where I learned this from. RM mentioned that the primary colours are red, green, and yellow, so why blue?
The funny thing is that we use RGB for some of our colour schemes as well. I was told that this was because yellow was a very expensive pigment, so blue is used instead.
Anyhoo, I found out more about rods and cones and it we do indeed see red, green, and blue.

What the.. I started sneezing a bit, and my eyes are itchy. Are my allergies acting up again?!?

I returned some stuff to a local SDM because I didn't read the packaging before purchasing. All I saw was the sale sign and picked up as many as I though I could handle.
In any case, it didn't take me long to get to badminton and I played fairly well today. The wrist is holding up and my elbow was okay. The wrist guard seems to be doing it's job, but I want to try playing with it off to see if I'm healing or if I'm just keeping it in a semi-injured state.
