    Recolouring

    gandalf458 Level 1
      I have found that I can recolour a selection of an image using Filters > Adjust Color > Hue/Saturation and playing with the H, S and L values. But it's all a bit hit-and-miss. Is there anyway to know what colour I'm going to get with particular HSL values?

          No, there isn't.

              To add a bit to what Linda said: resulting color of any particular pixel
              depend on *both* source color of that pixel *and* HSL sliders values.
              Therefore predicting the result, based solely on HSL shift, is in general
              impossible from math point of view.

                It's always a pleasure to see your comments, oh science of graphics
                guru. :-) I've learned a great deal from reading them.

                  Thanks Ilya. I was trying to recolour parts of a black and white image and succeeded reasonably well. I see the problems you describe if I start with a coloured image.

                    In Photoshop they provide a hue color guide of shorts at the bottom of the ap. That at least lets you know if you're heading in the right direction color-wise. Hopefully they'll carry that functionality over to Fireworks in the future.

                      IMHO, the real use of this "rainbow" thingie in Photoshop is that it
                      allows you to select some hue range for adjustment instead of adjusting
                      all hues simultaneously, and select "fade" transition borders for it.
                      *That* is definitely something well worth to be carried over to Fireworks.
