VB change color border menustrip but from external class

Question

I found the solution here on how change the colors in the menu. My question is related to the above old solution.

I can confirm that the solution worked fine on vb.net 2015 with framework 4.6.2

Color1 and Color 2 are inside the class.

Question is: how I can use Color1 and Color 2 from form_load1?

Let me report here the full code found (there are 2 answer and here is joint)

Public Class ColorTable
Inherits ProfessionalColorTable

Dim Color1 = ColorTranslator.FromHtml("#343D46")
Dim Color2 = ColorTranslator.FromHtml("#424B54")
