A study analyzed the relation of four information presentation methods--text, tabular, black-and-white graphics, and color graphics--to level of retention, reader reaction, and reading time. Results confirmed that the incorporation of color graphics in a document increases psychological reaction, but does not necessarily improve task performance.…

Discussion of digital document image processing focuses on issues and options associated with greyscale and color image processing. Topics include speed; size of original document; scanning resolution; markets for different categories of scanners, including photographic libraries, publishing, and office applications; hybrid systems; data…

Presents the Night Spectra Quest, a pocket-sized chart that identifies in color the spectra of all the common night lights and has an integrally mounted, holographic diffraction grating to look through. (JRH)

Discusses the interpretation of weather for children and shares program ideas to interpret the water cycle, thunderstorms (including fear of thunderstorms), and rainbows (including the colors of the rainbow). (MKR)

Shows that color blindness, whether partial or total, inhibits literacy acquisition. Offers a case study of a third grader with impaired color vision. Presents a review of literature on the topic. Notes that people with color vision deficits are often unaware of the handicap. (RS)

The effect of background color on the perception of color by students is discussed. Explanations on why students only see certain colors when viewing colored marks on a blackboard through different color filters are provided. (KR)

This study of the effects of lenses of different colors on the visual abilities and comfort of 20 patients with retinal disease found that, in home trials, the critical issue was density more than color. Office tests of visual acuity and contrast sensitivity with colored lenses did not predict subjective benefit. (Author/JDD)

Proposes a composite feature measure which combines the shape and color features of an image based on a clustering technique. A similarity measure computes the degree of match between a given pair of images; this technique can be used for content-based image retrieval of images using shape and/or color. Tests the technique on two image databases;…

Illustrates that acid-base indicators come in many forms and the reversible effects that acids and bases have on the colors of such indicators. An object is dyed in an indicator, which causes the object to turn dark blue at pH less than 3.0 to 5.0. Suggests using dyeable fabric shoes and other cotton articles. (PVD)

Examined exogenous orienting among infants between 7 and 21 weeks of age in 2 experiments using display with multiple potential attention targets. Found that as early as 7 weeks of age, sensitivity for a small moving stimulus can be significantly influenced by the simultaneous presence of competing attention targets. Found large increases in…

Proposes an alternative real valued representation of color based on the information theoretic concept of entropy. A theoretical presentation of image entropy is accompanied by a practical description of the merits and limitations of image entropy compared to color histograms. Results suggest that image entropy is a promising approach to image…

Discusses the appropriate use of colors in school libraries. Highlights include how colors affect students' learning and behavior; influences on users' moods; users' ages; the use of colors to bring out the best physical attributes; and the use of color for floor coverings, window treatments, furnishings, and accessories. (LRW)

Discusses the work of Helen Cowcher who writes and illustrates children's books dealing with conservation and ecology themes. Highlights include the use of color; involving teachers in the audience; career advice; and a list of titles with awards received. (LRW)

Presents an art lesson that incorporates self-portraits and a familiar art technique: coloring paper with crayons, covering the colors with a layer of black, and drawing through the black to reveal the hidden colors. Explains that the students must be expressive by using the colors or concentrating on their facial features. (CMK)

Previous research has shown that children systematically alter the size and colour of their drawings in response to the emotional character of the figures which they draw. However, these findings have been demonstrated only with children receiving mainstream Western education. This experiment was designed to investigate whether children receiving…
