Many people don't know how to match colors, but according to their own feelings, the results are varied and even interfere with the presentation effect of PPT.
The color matching of PPT is very important. Remember the color ring: imagine the square color drawing board that can be used to choose colors at will in the custom color window as a piece of colored paper, and imagine turning this paper into an upright small tube, then a color column composed of color rings from top to bottom will be formed. This is the understanding of the color ring. The 1/4 region of each ring, that is, within 90 degrees, is a color system. Then there are the basic color matching rules:
1, the color system within 90 degrees can be used for similar relations, and 180 degrees can be used to distinguish opposing relations. So you can choose the style you need to show.
2. Either choose different colors from the horizontal direction of this "colored paper" or choose from the vertical direction. Don't jump too much, it's abrupt.
3. Choose a dark background when the light is bright; or vice versa, Dallas to the auditorium
The PPT made in this way will be much more professional. Otherwise, experts can see it at a glance.
Give more! Hmm. How interesting
