Thousands or millions of colours

Hi

Hardly any of the visitors to my site are constrained to 256 colours. Nearly all have browsers capable of seeing thousands or millions of colours.

When selecting colours in FW are some colours only safe for use in browsers that support thousands of colours (as oppose to millions)? If so how do I know which are suitable for thousands of colours?

Thanks

Mark

You should be fine just using the regular color palette options. If you are talking about images then the amount of colors, more or less, helps determine the file sizes of the images rather than what monitor you hope your visitors will view it on. However with everyone, in some way, not having their monitors calibrated or not using proper profiles you can never guarantee you’ll hit the absolute correct color anyways.

I’m pretty safe in saying that the days of web-safe colors are pretty much behind us with the advancements in technology. It’d be a rare moment to run into somebody using a Commodore 64 these days but you never know Paul Dunning on here has been running an Acorn.

You’re right, Dan. However, I think that he’s asking about the preference setting in FW that gives you the option to chose between both color mode. By default we have it in thousands of colors…

Mark,
take a look at this thread, back in 2008:

Good call Marcus. It is somewhat debatable though as it doesn’t say anything about Document Setup and it does touch a bit on web-safe colors in regards to monitors.

Either way good find on the thread and hopefully it helps Mark with his inquiry.

Hi Marcus and Dan

Thanks for your comments. I’d had a look at that thread before posting.

What I am trying to say is, (but rather clumsily):

When making a colour in the FW Colors pallet, I tend to use the RGB sliders. Are there RGB colours that are not suitable for monitors with thousands of colours, but work on monitors set to millions of colours?

i.e. there are ‘web safe’ 256 colours. Are there ‘web safe’ 1000’s of colours? And if so, how do I know which ones they are?

That setting has nothing to do with the images that are converted to
display in your site. It only governs the compression used when saving
the proxy versions of the images, which Freeway stashes in the
Freeway document itself. These images are used on screen, in the
design view, to speed up your interaction with what might be 300ppi
publishing quality images. In a pinch, these images are also used to
fill in for an original that’s gone missing. But otherwise, they are
simply a way to make the everyday design experience more speedy.
Setting this to Millions will only cause your Freeway document to be
larger when you save it, and may make the page-flip experience a
trifle slower. On a modern Mac I doubt you would notice either effect
on a practical level.

Web safe still has its place, but it’s not as important as it once
was. The entire point of the Web safe palette was to choose some
colors which stood a better chance than others of appearing
‘relatively’ the same on a wide range of monitors/browsers/operating
systems.

The point wasn’t that you could line them up in a conference room and
all monitors would show the same color, it was that if you chose a
color further in the green direction of the cube, it would appear to
be greener, rather than, say, browner.

Particularly within lighter colors, very often what looks different to
you may not have any contrast at all on another monitor.

I work back and forth between two Macs; a Mac Pro with Cinema displays
(fluorescent backlight), and a non-glossy MacBook Pro 17 (LED
backlight). Despite lots of effort with the ColorSync controls, I
still cannot reliably see the same color on both of them. Things which
pop off the screen on the MacBook are flat and restrained on the
Cinemas. And that’s just on a Mac. When I (occasionally) look at my
work on a client’s computer, I get another surprise. When I see it
projected, I sometimes wonder why I bother to use color at all.

The color-safe palette takes colors which are a precise distance from
one another and arranges them for you to use. It’s the distance,
rather than the colors themselves, that is important here.

All I can say is test, test, test! If you go into the nearest big-box
store and look at their wall of televisions all playing the same loop,
you’ll see wild variations in color and contrast there. The computer
displays are no different, and when you through Windows into the loop,
the grasp of reality gets even more tenuous.

Websafe was a subset of the 256 colours available in the GIF format. The idea was to ensure that GIFs looked the same between different browsers and different platforms. REmember, this is a time when not all computers could display 32,000 colours without impacting on screen resolution. My first Mac, a Performa 630, could only display 32,000 colours at a resolution of 640x480. If I wanted the full 800x600, I got 256 colours.

The same was true of Windows - and, if you want to go even further down memory lane, Acorn machines.

Each OS had its own palette of colours for 256 colour modes - the “web safe”palette aimed to span as many different platforms as possible, so an image would look as similar on a Mac or a PC as possible.

There is no “web safe” palette for colour counts higher than 256 colours, and I would say than unless you were some kind of retro computer geek running an obscure computer from the 1990s, this is not going to be of any major concern.

Here’s a handy Wiki article about such things.

Thanks everyone.

I’d seen the 256 “web safe” colours in the FW pallet and was wondering if there was a pallet for the 1000’s of colours. Obviously not.

Thanks for clearing that up
