    16 bits color?

    Peter Lorent Level 2
      A client complained about the colors in a movie. As it turns out they see boundaries of mc's and text fields (in text fields it's the rendeing area of the text, not the complete text field) in a slightly lighter tint than the background. I tried to replicate it and had to set my display to 16 bits.
      Solution? Limit the color scheme to web safe?
      How 'common' is 16 bits color? Isn't this something from the middle ages?

          There are a lot of persons using 16 bits, and must of them don't know what Color Depth means... :(

            about 3% of users are using 8bit color (presumably handhelds like cellphones and pdas but maybe some dinosaurs) and 16% are using 16bit color.

            the other 81% are using 24bit or 32bit color.

              So, am I to understand from your answer kglad that I can't prevent the 'bad' display on a 16 bits graphics card?

                Not unless you restrict your palette to 256 colors (Web Safe).

                  Thought as much. Thanks for the reply.

                      Web safe probably won't help (it may be slightly better, or may be worse)

                      The problem is a bug in the player .. it renders solid colors differently to
                      image / gradient fills (and in some other cases). its also uses different
                      rending when transparency is involved

                      If the problem is due to a solid color fill being next to a gradient/image
                      color, then you can solve the problem by using a gradient with only a single
                      color in it for the solid fill.

                      Apart from the fact that web safe colors are not web-safe at all (apart from
                      a handful, like a handful of blues and the primary colors) it really won't
                      make a significant different (the web-safeness of the color is not the
                      issues here)

                      Just have a think on this for a moment .... No matter WHAT color system you
                      use on a screen (8-bit, 16-bit, 24-bit, 32-bit), if the PC is trying to
                      output a given RGB color, it will display the same everywhere on that screen
                      .. it may be different to what some other computer would show, but it would
                      be consistent across the screen. So the problem is that Flash really is
                      trying to display different colors on different pixels where it should be
                      trying to display the same color (if it wasn't for the bugs in how it
                      renders). Now, changing what color is there may increase or lessen the
                      visible difference, but it is unlike to help (unless you do something like
                      use pure black or pure white etc, which I think Flash manages to get right)

                      NOTE: There is a technote that tries to explain away why this happen so it
                      doesn't look like it's a bug (technotes are good at that). But it really is
                      a bug.

                        you're welcome.

                        but i'm not sure about restricting your color palette helping those 16bit users unless you were using a colored text or the text was on a colored background that they could not reproduce because of their system limitations.

                          Jeckyl (thanks for the detailed explanation - very helpful in the discussion with the client), kglad,
                          No, it doesn't help much, using a 'web-safe' palet. The problem persists and is also better/worse across different machines, using a graphics card or with integrated graphics.

                          >Now, changing what color is there may increase or lessen the visible difference, but it is unlike to help.
                          Exactly what happens.

                          Well, let's see how the client reacts...

                          Thanks guys!
