What principles do PPT color matching generally follow?
1. Harmonious tones and comfortable layout.
Color matching in PPT is actually a very difficult thing. You need to be familiar with colors, have experience in color matching, and be able to control the overall color in a harmonious state. As well as the layout of the entire set of PPT, it needs to be unified and pleasing to the eye, which requires the producer to have strong overall control.
2. Color ratio
Normally we recommend that a PPT set should have no more than three colors.
PPT picture color generally consists of three parts: main color, auxiliary color and embellishment color.
The main color determines the style of the entire PPT to ensure that the information is conveyed correctly; the auxiliary color can help the main color establish a more complete image, making the picture richer. The existence of the auxiliary color is necessary, and there is a main color Even more advantageous, a page without auxiliary colors would be incomplete; the function of embellishment colors is reflected in the details, scattered and smaller in area.
In principle, a complete page must have main colors and auxiliary colors. Embellishment colors can be added as appropriate and are non-essential colors. The fewer colors used, the better. The fewer colors, the simpler the picture and the more mature the work will appear. Of course, there are also special circumstances, such as some festival posters, etc., which require a lively and energetic atmosphere in the picture. The colors can be more, but the more colors there are, the more attention must be paid to the color ratio, otherwise the picture will be very chaotic and difficult to control.
The golden rule of color matching ratio: 70% main color, 25% auxiliary color, 5% embellishment color
For example, in interior space design, 70% should be used for walls, and 25% for furniture, bedding, etc. Other small decorations account for 5%; for example, men's jackets, 70% coats, 25% shirts, and 5% ties. This golden rule is very correct at any time and place.
The general basis for distinguishing main colors and auxiliary colors is the size of the area used. We usually use dark or highly saturated colors as the main color; similar colors, adjacent colors or complementary colors are used as auxiliary colors, which are worth mentioning. What I want to mention is that as neutral colors, black and white are easier to match with other colors. We call them universal auxiliary colors, which can basically be used as auxiliary matches for any color. For decorative colors, we generally choose colors with high saturation or high brightness.
