How to use it?

This add-on sets up a tab in the n-panel (press n key in 3D View). Open by clicking Colorful tab in the n-panel. Make sure you are in SOLID view.

• The panel has a Color Picker.
• Select your object and pick your choice of Color in the picker. The selected color will be applied to the object in solid view.
• Below the SOLID view you have the shortcuts to easilt create standard primitive objects with the selected color.
• You also have an info text what is the current active object where the color will be applied.  
• You can also select multiple objects and pick a color, which in turn applies the selected color to all selected objects.
• When you move to Wireframe, Material Preview or Render Preview mode, this addon will display a warning in Red and Color Picker will not be shown as these colors are not applicable for Material View & Renders. It also shows a handy button to switch back to SOLID view.
