B4R Code Snippet ByteToRGB algorithm

Greetings,
Most of the data that I am processing for use with WS2812B LEDs is 8 bits and the WS2812B libraries (rNSRainbow and rAdafruitNeoPixels) require RGB format. So I needed a way to convert bytes into RGB. I remembered having done so in an earlier Arduino project and was able to translated the algorithm into Basic. The following Basic code can produce a full range of 256 colors.

I'm not an expert programmer and cannot explain exactly how the code works, but please let me know if you have any suggestions or corrections.

' Input a value of 0 To 255 to get an RGB color value. The colors are a transition r - g - b - back To r.
Private Sub ByteToRGB(Value As Byte)
    If Value < 85 Then
        'Log(Value * 3, 255 - Value * 3, 0)
        Strip1.setColor(LedNum, (Value * 3), ((255 - Value) * 3), 0)
    Else If Value < 170 Then
        Value = Value -85
        'Log(255 - Value * 3, 0, Value * 3)
        Strip1.setColor(LedNum, ((255 - Value) * 3), 0, (Value * 3))
    Else
        Value = Value - 170
        'Log(0, Value * 3, 255 - Value * 3)
        Strip1.setColor(LedNum, 0, (Value * 3), ((255 - Value) * 3))
    End If
    Strip1.show
End Sub
