Hi all -

apologies in advance if this has been asked....new to the board.

I have purchased and imported some .png files into my pages ('08) document. They are black....Any way to change the color? All instructions seem to be for Photoshop. Can I resave as a different type of file to enable this?

Thanks

    Before you attempt to troubleshoot in Pages, try to troubleshoot the image itself in Preview. This way it is simpler to see what is possibly the problem. Do as follows and then post what you find:

    1. Launch Apple Preview and open the PNG format images one by one - what do you see?

    2. Look in Apple Preview > Tools > Get Info > ColorSync Profile - what do you see?

    3. Look in Apple Preview > Tools > Get Info > Color Model - what do you see?

    The color model is RGB and the ColorSyne Profile is sRGB IEC61966-2.1......which unfortunately means nothing to me.


    The colour model and the colourimetry defined by the ICC profile match (sRGB or Standard RGB is a colour space equivalent to HDTV and specified by Microsoft and Hewlett-Packard in 1996).

    In other words, colour management is not part of the problem.

    black design with gray background...although the background is transparent in the document


    So in Preview the background is transparent and you see only the black design? And in Pages the background is transparent and you see only the black design, too? That is, Preview and Pages agree in relation to what you see? Or?

    Are they supposed to be black and you just want a different color, or are they supposed to be full color but are rendered black instead?

    You can achieve some limited color change by using Adjust Image. However, you won’t be able to pick a precise color. (It’s not a color chooser.) Start by moving the Brightness slider all the way to the right, then play with the Temperature and Tint sliders in different combinations until you find a color you like. You may want to go back to the Brightness slider and try different positions there, also. It’s hit or miss, but it will give you some color.

    Pages is a word processor and page layout program with just a few graphical options. There are quite a few graphical application to download from Internet. Some are free and some you have to pay for.
    Inkscape is free, EazyDraw can be tried out before buying. There are many more.

    If you want to correct the pixel colourants (the colourant model / the colourant format), and either keep the ICC colour space that defines the colours of your colourants or change the ICC colour space in your PNG file, there is for instance

    a. Adobe Photoshop light for cloud computing (not tried it)

    b. Google Picassa for cloud computing (not tried that either)

    There are also vector based drawing products that to a degree work with pixel colourants, but this tends to be like trying to use a screwdriver as a chisel, an axe as a hammer, or a pipe wrench as a spanner (which in my experience wrecks the grip on the nut).
