Color contrast on website series1

Question:
How do you use color contrast on website to strength and exaggerate color effection? Presume it is for people with visual impairment.

Analyze:
Color contrast on web is no more than color text against uncolored background, uncolored text against color background and color against each other.
A good example uncolored text against color background which RNIB has done to show the large scale color background strength the contents discrimination.
I would like taking a try on color text against uncolored background to achieve the same effection,though QAC has done in a bad result :(

It seems that the size of preview window are fixed, though the window for WORD documents look bigger.

The highest color contrast = The most legible solution on screen?

As my earlier article said, black and white provide the highest contrast, and similar color paris such as white and yellow on black and blue background could produce the highest color contrast as well.

Is that mean it will determine the best choice for screen text reading?

Some public cases shows when a message or instruction involves a more complicated explanation, black and white provide the highest contrast this does not always provide the most legible solution. The book “about face” gives a obvious example to support this idea: British road signs using white (sans serif) lettering on a dark-green background; “hazard warning” signs where black letters are used on a yellow background.

Is it possible that the message or instruction on web involves a more complicated explanation?…
Therefore why do you believe it is safe to choose a black color type?

Does x-height really matter when choosing fonts in using for readability and legibility?

If using a typeface with a low x-height at a large point size, wouldn't it has the same result as using a medium or large x-height smaller point size. So does it means x-height only useful when setting very small like 6 point size fonts?

Why not use san-serif fonts on print design?

It's better to use san-serif than serif fonts on web, as their simpler letter form remain readable at low resolution. serif fonts need more pixels to display their extra details. I was wondering why I seldom see any san-serif fonts for body text on print design?

Apply the legibility principles to screen reading

Questing for "Apply the legibility principles to screen reading"

Here is Berin Loritsch’s answer from the dictionary definitions.

Readability - Typography . the property of type that affects the ease with which printed matter can be read for a sustained period.

See more his words, practically speaking……

Snlchina gave a more clearly definition about these two words.

Readability is most often and more properly used to describe the ease with which written language is read and understood—it concerns the difficulty of the language itself, not its appearance. Factors that affect readability include sentence and word length, and the frequency of uncommon words.

In contrast, legibility describes how easily or comforably a typeset text can be read. It is not connected with contentor language, but rather with the size and appearance of the printed or displayed text.

Wikipedia gives “Readability” a widely definition.

Readability in English has different meanings. One relates to the ease of reading and understanding a text. Another meaning relates to the ease of visually recognizing letters, numbers, or other symbols on a page, sign, or electronic device. In English, this second meaning is generally referred to as legibility to which another article is dedicated. There is a third meaning related to the sufficiency of embedded documentation in computer-program code, described in the section below, "Readability in computer programming."
