Hi Inferno, -- I believe that this has been said, but let me repeat it. -- . 1. Colors are not preserved for the blend (merge) modes when switching from CMYK to RGB or to Lab in Photopaint. Photoshop issues a warning for changes made to the color mode. Photopaint usually does the same. 2. So what's preserved if anything. 3. Just about nothing is preserved. Arithmetic is carried out in accordance with the name of the merge (blend) mode. For instance, in the ADD blend mode the numbers are added for each channel. If you can predict the color after adding the sRGB channel numbers -- say -- (7, 124, 175) and (53, 85, 135) -- then you have supernatural powers. 4. You can even run into trouble by converting from one RGB space to another if you have a transparency overlay in DRAW or layers in Photopaint or Photoshop. 5. There's a very good reason why not all modes have a blend mode. The arithmetic would give colors which are impossible or ridiculous. If you want to learn more about what happens to numbers and maybe color with blend modes, see "The Hidden Power of Blend Modes" by Scott Valentine. If you can predict the color after reading the book, let me know how to do it. It's still a mystery to me. I use the Lab mode in Photopaint for my newsletters. I know full well what to expect if I lift the right side of the b Curve. There is nothing that simple in DRAW. I do all drawings and photos in Photopaint's Lab mode. Then when all looks OK, I flatten in Lab. Then and only then do I convert to CMYK. I only convert to CMYK because the printer will yell at me if I give him a Lab file. Phil
