      True Dave, the default color can go it alone....

      As for grey scale variation, If we didn't have variation i think it would shade quite bland IMHO...

        Andrew, you have a point about the potential for blandness. (I think I just made up a word.)

        I'm sure it would add to the complexity of the plugin but suppose one could choose some sort of filter factor. Suppose that you want to simulate a 25 Red filter. You might choose Red from a list of filters which would give green colors lower values (make them darker) while reds would tend to be higher values. This would give you the ability to tune the grays to prevent some colors from being too close together on the gray scale.

          Here's another example of using the Grayscale Plugin. This is raw SU output.

              Thank you Andrew. There's not much color in this model anyway but I like the effect with the grey scale option. I like that the wood grain still shows this way, too.

                do I understand it correctly that with this method you could even create a sepia effect (with some colours standing out of course πŸ˜‰ ). that would be such a cool thing!

                  I hadn't thought of it that way but I suppose since we're asking for the moon...

                  I was really thinking more of "filters" for controlling values of gray to preventtwo adjacent colors from looking like the same value of gray. I'm sure you've seen the example from the old photography texts of the red, green and yellow apples shot through different colored filters on black and white film. I tried to find that photo in a quick Google search but came up empty.

                    I'm sure it can be be done, although I don't know the math involved in filtering/masking colors. To combine the ideas, a set of filter settings could be saved as a preset - named Sepia, or Black & White, as examples.

                    off to day job... later.

                          Greetings Jim:

                          This plugin is a great addition. We can now insert
                          a pdf from Lay Out and import it into cad programs
                          like Vector and make a BW presentation on the actual
                          Construction Documents.

                          Thanks,

                          DonVid

                              I made 2 small updates:

                              1. Right-clicking Groups and Components gives you the Revert Color option.
                              2. Implemented the suggested grey color calculation of: color = 0.3 * red + 0.59 * blue + 0.11 * green

                              Download it from the first post of this thread.

                              Hi

                                Hi Jim,

                                Thanks for the update. I see when opening the script that you have added the math. I don't see the Revert color option when clicking on a component, though. Is it just me?

                                  I get the Revert on Components. I honestly didn't try it until just now... but it does work. Now, if each individual Face in the Component is colored (as opposed to having the default color), you need to open the Component and right-click a face.

                                  Hi

                                    Oh, I see. I almost never paint components. I always apply the material to the faces so I didn't understand at first. Now I do.

                                    Thank you.

                                          Jim,

                                          This is really a great plugin.
                                          I have already used it for some presentationdrawings and it works fine.
                                          Today I was playing with it again to define a nice match between specific colors and their grey-scale-representation and now, for the first time, I tried to go back and forth between grey-mode and color-mode and..........
                                          it isn't possible (my mac or my partial blindness maybe ?).
                                          The color mode in the pop-up menu is greyed out (so not functional) and I cann't find any 'revert color' option anywhere under my right mouse button. Neighter when selecting a group nor when going into the group and selecting seperate faces nor within the color-picker. 'Undo' doesn't do the trick either.
                                          Nowbody mentionned this 'problem' before, so I guess I must be overlooking something.
                                          Please help me look in the right direction to find my way back into color.

                                          By the way, I really like the fact that your plugin doesn't effect the standard face colors (back and front) so you can high-light special details in one or two vivid colors. Whatever additions you ever make to this pugin, please keep that possibility in.

                                          greetings,
                                          Ton
