So what if the user types a color not in the list of system colors or so? If you don't want to give color dialog, give a dropdown of fixed colors and use the selected color.

Color myColor = Color.FromName(textBox1.Text);
if (!(myColor.A == 0 && myColor.R == 0 && myColor.G == 0 &&
    myColor.B == 0))
   this.BackColor = myColor;

If the color is not a predefined name, then it will return 0 to all of the ARGB elements.

Does it take care of all sorts of valid color names & validation(like caps)? Or will it be just System colors?

I believe it has to be a KnownColor. These are found at

But, if the user typed "Light Blue", it wouldn't work because the KnownColor is "LightBlue". I agree that picking color based on what the user types isn't the best method.

Got it! Yet what you suggested looks a fit to what OP needs. Nice one.

You need to write a good algorithm in such case.

There is plainly no API that cN magically decipher any terminology possible for any color. So, a drop down is what you need.

If a KnownColor is entered in a text box, you can actually do a conversion.

See here for a list of know colors.

While factually true, this doesn't actually help. The only solution on that page is to use the enum KnownColor to return a color or to use the RGB value, not a text value.
