Is it legal to sell image of custom gradient with slices of Adobe Photoshop Gradient Editor

I am new to selling online. I'm wondering if it's legal to sell a gradient image made in Photoshop with slices 
of small images of Gradient Editor from Photoshop which describe features of gradient like the one in the 
picture. Is it legal to sell pictures of parts of Adobe Photoshop software that are in the main picture as 
shown below the gradient picture? To describe the gradient, I cut out a part from Photoshop and put as an 
example what can be seen at the bottom of the image. There are three images of the gradient that are 
actually slices of Gradient Editor in front of which is a description of the color.
