(1) White background: black, red and blue characters can be selected. If you feel that it is not rich enough, you can change the local background color.

(2) Blue background: dark blue is preferred, and it can be matched with white text or yellow text (light yellow and orange), but deep red should be avoided. This is the most commonly used, safest and simplest color scheme.

(3) Black background: with white characters and yellow characters (orange is better than light yellow).

These three color matching methods can ensure the quality of slide show. If this is the first time, it is highly recommended. Generally speaking, slides should not only have text, but also add pattern diagrams or flow charts to add color to the slides. You can also add a little lace, add a line between the title and the text, or insert icons of schools and hospitals to avoid the monotony of the slide show.

Extended data:

Key points of production:

1, font not less than 18 point, line not less than 1.5 point. So that the audience sitting in the last row of the conference room can see it clearly.

2. Avoid using too many fonts and reduce the use of underscores, italics and bold.

3. Try to use fonts with the same stroke thickness in slides, such as bold, Arial and Tahoma.

4. If you use English, don't use all capital letters. On the one hand, it is disrespectful to the audience (spelling in capital letters means yelling at others), which is not as easy to identify as lowercase letters.

5. The font of the text is slightly smaller than the title, so don't fill the slides with text. If there are too many words, I'd rather divide them into multiple slides.
