Change the string at the end of System.Drawing.Color. in Blazor [closed]

I want to change the color mentioned at the end of the color names. For example, if we have System.Drawing.Color.Red I want to pass a string variable to change the Red to say, Pink or Orange after a user types it in an input field and presses a button. So System.Drawing.Color.(variable)

How do I do that?

This will be used to make an xml Component attribute as below:

<ComponentName color="System.Drawing.Color.(variable)" />

How can I do this?
