I have the hex value. That hex value IS the ColorValue. VB can accept numerical values in decimal or hex (or even octal). ColorValue = &H00FFFFC0& Red = ColorValue And &HFF& Green = (ColorValue And &HFF00&) \ &H100& Blue = (ColorValue And &HFF0000) \ &H10000 Try it out. Rick

The hex represents the Blue, Green, and Red values in 1-byte hex format: xx BB GG RR Light Blue: 00 FF FF C0 Set a form's backcolor to some palette color then check the backcolor property. It should be showing you the hex value, which is the color value you selected.... LFS

For example, for the light red, it requires the RGB values of 255, 224, 224 which correspond (close, not exact) to the hexadecimal values of C0C0FF. How do I obtain 224 from C0? 255 from FF? If I remember, C is 13 and 0 is 10, F is 15. I have the hex values from the Properties color palette in VB6. That is where I got the hex values of the 4 colors in my original post and the basis of the colors that I need to put into the graphics program that I am using. I found a conversion calculator on the net, but am having trouble getting the shade of color that I want. I know the colors will differ on different monitors. I want light shades of the colors. That is why I am using the color palette in VB6 as a starting place. Thank you, Jim Y

Form1.BackColor = &HC0C0FF Form1.BackColor = RGB(&HFF, &HC0, &HC0) Form1.BackColor = RGB(255, 224, 224) These three statements produce the exact same color. You already have the hex values, so use them in your calls. Unless you need to send text, hex and decimal values are equivalent / interchangeable. In the Hex notation, the order is BBGGRR In the RGB function, the order is RR, GG, BB Experiment with it a little, it is not difficult.... LFS

And hex of 224 is E0. ?Hex(224) E0 Those values from the properties window are all RGB and the most significant byte is not used - it is always 00, as far as I know. Only system colors use that byte and, I think it is always 80, which is just a sign - means they are always negative values in a signed presentation of 32 bit value. For a proper way of extracting each color's value see Rick's answers above. Dmitriy. |
