Showing a color preview even for the descriptive color names

Currently, Qt Creator shows the color preview when the color value in hex in the editor is hovered over by a mouse cursor, which helps a lot. 
I think it would be better if we could also see the color preview for the colors described with names, such as "red" or "black." 
They seem obvious and I know it feels unnecessary, but there are some colors which are difficult to imagine how they exactly look. 
For example, it's difficult to see the difference between "gray" and "lightgray" just by looking at the names.
This could result in the user needing to look up the color on google to check how it looks, which could possibly cut the focus of the user while working on the development.
