Lets say we have a webbrowser and we want to convert the background colour to RGB and VB, here's how to do it! (webbrowser1.document.bgcolor will return "#aaffff" or similar)
a = Webbrowser1.document.bgColor
R = Val("&H" + Mid$(a$, 2, 2)) ' Value 170
G = Val("&H" + Mid$(a$, 4, 2)) ' Value 255
B = Val("&H" + Mid$(a$, 6, 2)) ' Value 255
result = rgb(R,G,B) ' reult is a vb color value (LONG) = 16777130
