Various studies have shown that color-use influences learner attitudes, comprehension, and retention (Gaines & Curry, 2011). Some of these influences are broadly universalizable, others are contextual to the learner’s age, gender, or culture, and others are contextual to the subject matter or learning objectives being targeted
The claim that some of these influences are "broadly universalizable" and others are "contextual" is somewhat arguable. While it is true that cultural and contextual factors can influence the way learners respond to color, it is important to note that some basic color associations and effects are fairly universal across cultures and age groups. For example, the color red tends to be associated with danger or excitement, regardless of cultural background. At the same time, it is also true that the specific effects of color-use may vary depending on the learning objectives and subject matter being addressed. For example, the use of warm colors like orange and yellow may be appropriate for a lesson on creativity or innovation, but might be less effective in a lesson on analytical thinking.
