Art, web design: what is saturation?

Different perspectives on color lead to self-tutoring: the tutor shares ideas about saturation.

Saturation is the opposite of gray. (See my post here about gray and grayscale.) Gray can also be written grey (see my post here). However, my sources about color seem to prefer the spelling gray, so I follow their lead.

Saturated means “pure color”. I’ve, at times, imagined “saturated” color as dark or vivid. In some cases the perception makes sense, from a practical point of view.

In the rgb (red, green, blue) system, gray is an equal combination of all three. Therefore, a color can be imagined to exist “on top of gray”. For example, the css color chocolate, versus its saturated counterpart:

chocolate background

chocolate background, gray subtracted:
“saturated” chocolate

English, Web Design: what does deprecated mean?

Tutoring English, fresh vocabulary keeps writing interesting. The tutor brings up a term he reads in connection with computer science.

deprecated (adj)

viewed unfavourably, viewed with disapproval.

In computer science, certain ways of writing code can become deprecated after newer, preferred ways supplant them. The deprecated code may continue to be supported for a time, but after being labelled “deprecated”, it’s vulnerable to sudden dysfunction.

Art, web design: gray and grayscale, part 0

Self-tutoring about color theory. The tutor mentions gray and grayscale.

From the red, green, blue (aka rgb) point of view, gray is composed of equal inputs from each. There are many lightnesses of it.

gray: rgb(n,n,n)

Any flavor of gray is on the grayscale.

Gray is not a color.

Food: dark raisins vs golden

More self-tutoring: a question crystallizes in the tutor’s mind, so he looks up the difference between dark raisins and golden ones.

Talking about raisins produced in California, dark raisins and golden ones commonly begin as green grapes (typically, Thompson Seedless).

If the grapes are dried in the sun, they brown – hence, dark raisins.

If the grapes are dehydrated out of the sun, in managed humidity, golden raisins can result.

Biology: pH range of blood

Tutoring biology, as well as hearing new ideas about nutrition, might lead to the topic of blood pH.

On the pH scale, 7 is neutral, below 7, acid, and above 7, alkaline (or base).

Human blood pH range, for health, is between 7.35 and 7.45. For survival, it’s between 6.8 and 7.8, according to conventional wisdom.

Psychology: recognition

More self-tutoring: the tutor discusses a group dynamic.

I’ve been traveling as a chaperone lately. Not often do I spend time on the road with a group, but this weekend I am.

An absolute necessity, when moving in a group, is that it stays together. Yet, with many other groups around as well, getting lost in the shuffle can happen. How do people avoid it?

One rule of thumb I’ve relearned this weekend is to notice a “key character” – often someone who wears a distinct coat or accessory. They’re easy to spot, which their cohorts soon realize. The entire group might be drawn – and kept – together by their recognition of that peculiar hat, shirt, shoes or coat worn by that key character. Just as likely, the key character doesn’t even realize they’ve become the lynchpin.

Recognizing a peculiarity of one of my groupmates, then seeking it and staying near, is how I got by as a kid. I’ve relearned the habit on this trip.

Thank you to all who wear distinct hats, coats, etc. You likely don’t realize how important you are:)

Lifestyle, health: sleep: do hours before midnight count for double?

More lifestyle self-tutoring: the tutor begins research about the question of sleep quality before midnight vs after.

I first heard the adage “hours of sleep before midnight count for double” from a judo coach. I trust he’s probably right, though I’ve no specific idea why.

Today I started looking for a reason and encountered organicolivia.com, where I read interesting logic that supports the claim of hours slept before midnight counting for double those after.

Olivia’s point is that the functions of sleep – starting with falling into proper sleep – are energy-expensive. Hence, the reason that when overtired, actually falling asleep can be difficult.

Olivia observes, then, that during the hours before midnight, you still have energy “left over” from the day. If you spend that energy in a productive, wakeful activity between 9pm and midnight, your body won’t have it to invest in sleep past midnight.

Olivia’s claim sounds logical to me. I know that going to bed an hour earlier, then waking an hour earlier, seems easier than staying up another hour when I’m tired.

I hope to pursue the sleep-before-midnight concept in future posts:)
