I've always had a high sensitivity to color, so it was very noticeable to me. I'd say it lead to me to entering the arts and my love of telescopes.
Many males suffer from varying degress of color blindness, so I've always felt rather lucky.
That begs the question, do you other guys see the difference between the tube clamp's color and the focuser and cell?
I can see stronger color saturation on the clamp as apposed to the cell but the hue looks the same on both parts.
My wife could see colors that I didn't know existed. I had to ask her to look at a resistor's color band, that I couldn't discern. I ask, " was it blue or violet?" (it has to be one or the other to be part of the standard color code) She replied ,"It's neither." and
named it as a color that I think only women know about, which was no help to me....
