- RGB VBA
- RGB for html
- How to convert
The RGB function in VBA returns the code that represents the mixture of red, green and blue. All Red?hex(rgb(255,0,0))
so rgb(red,green, blue) simply does this – which is in fact right to left bbggrr
hex(blue * &h10000 + green * &h100 + red)
But RGB codes in html/css ( for example “style=color:#ff0000”) read left to right, so we need a function to reverse them to generate an html style color code.
Public Function rgbToHTMLHex(rgbColor As Long) As String Dim r As Long, b As Long, g As Long ' extract components r = rgbColor Mod &H100 g = (rgbColor &H100) Mod &H100 b = (rgbColor &H10000) Mod &H100 ' just swap the colors round for rgb to bgr rgbToHTMLHex = "#" & maskFormat(Hex(RGB(b, g, r)), "000000") End Function Private Function maskFormat(sIn As String, f As String) As String Dim s As String s = sIn If Len(s)
