This logo tires to convey the idea of diversity through the simple shape of a circle or a dot. The different sizes and colours of the dots represents the diversity we see in various performing arts, visual arts, music, languages etc across the world. The dots together forms another circle which represents the world\ globe.
The simplicity of the logo would make it usable across media. While colour is used to emphasize the idea of diversity the logo is usable in single colour too. The idea of diversity is still brought about by the dots of varying sizes.
A few examples of the logo in use have been included in the images.
