Krish and Paranita visit the local swimming center and see that there are hardly any people there. They want to encourage others to learn swimming-a very useful skill to have. They decided to make a poster and put it up in their school.`Making a poster. Time to write

Answer and Explanation:

The poster should have a classic image of a person swimming in a pool. This image should be large and extend across the poster, allowing people to view it well.

As this image will tend to have a bluish color, we should write about it with a color opposite to blue, to draw people's attention and make the poster attractive to the brain. If we look at the chromatic circle we will see that the color opposite to blue is orange, so the letters must be orange.

On the poster, the name of the local swimming center and its address will be written centrally at the top.

Below is the invitation for the population to participate in swimming training, in addition to showing information on how free and beneficial participation is. Next to the article can be shown the times when swimming can be offered in the center.
