Photoshop tutorial - Making a real looking rainbow (partial and full arch) level: beginner

Attention: You may need to pause the video periodically to read instructions I made this video because not too long ago I wanted to know how to make a real looking rainbow and not use someone else's hard work for my own projects. It's not perfect and there may be better ways to do this - I just thought I would pay it forward for those who want to know how and do not. Thanks for watching!
