Dim Color As Word
Color = Color24to16([R], [G], [B])

Convert 16 Bit back to 24 Bit colors

Dim R As Byte, G As Byte, B As Byte
Color16to24 [16 Bit color], R, G, B

Alpha blending of 2 16 Bit colors

Dim Color1 As Word, Color2 As Word
Dim Mixedcolor As Word
Mixedcolor = Color16alpha(Color1, Color2, [Alpha 0 (Color1) - 31 (Color2)])

Included is a list of constants with 500+ named colors, which are also listed in the corresponding Excel-sheet and an example how to define custom color constants:

Const Color_custom =(((RED_8bit * 249) + 1014) And &HF800) + (Int(((GREEN_8bit * 253) + 505) / 32) And &H07E0) + Int(((BLUE_8bit * 249) + 1014) / 2048)
