Combinations
· Don’t use too many colors or too many shades of one color.
· Keep graduated backgrounds subtle and smooth.
· Be careful which colors you use together.Very bright colors scream at your audience and tire their eyes. Some colors will “vibrate” against each other and make the visual too difficult to read;they make the visual look blurry.
· Do not use blue on black (Fig. 14).It looks out of focus.
· Do not use red and green together(Fig. 14). Studies show that 7–9% of males and 1–2% of females are color deficient,which means they don’t see all colors. Red and orange are confused
with green and yellow. If your visual is green with red text, some individuals
would see only one color with each slide.
· Keep a consistent color scheme throughout your presentation. Consistent graphic elements should be linked from frame to frame. Titles should be the same color, similar data variables should be the same color, bullets should be the same color, and so forth.
· Different media project color differently.Film recorders, printers, video equipment, and computer monitors interpret colors and show them differently.Consequently, there may be a vast difference between the colors on your computer screen and those on your output device. Also, everyone sees colors differently.If color accuracy is critical, make test visuals and consult with those who will be imaging your slides or printing your poster.
