    I am working on some drawings which I have scanned and have to change the colour of it. More precisely, the drawing are china ink on white paper. therefore I have black lines on white background.
    I want to change the color of both the black lines and the background. (i.e. pinck lines on purple background).
    can anyone help me with this?

    the drawing is quite complicated so I cannot work with the magic wand. also replace colour feature does not work with black or white.

    thank you

    If you have scanned the images as a monotone bitmap (i.e. not greyscale or colour) and it is of sufficient resolution and you have Adobe Illustrator or InDesign, all you have to do is:
    • Open a new AI or ID document
    • Draw a rectangle and fill it with your chosen background colour
    • File>Place the bitmap image on top of your background rectangle
    • Apply colour to the bitmap image just as if you were adding colour to any other object
    • Done
    In the days when Quark XPress ruled the roost and vectorization software was a bit hit and miss, this was how 'linework' bitmaps were generally dealt with.

    Create a new document with a background layer and a layer filled with the colour you want your artwork to be. Then, create a mask and drop the black and white artwork into the layer mask.

    Use the pen tool to trace the drawing, then make it a selection. Then go to image -> adjustments -> hue saturation

    I would use invert (command-I) so you have white lines on a black background, then apply a Hue/Saturation layer over it, select the "Colorize" box and go from there until you have the color pink you like for the lines. Then create a new layer on top of everything, color it purple and select "Overlay" for the blending mode. Finally, drop the opacity of the main layer (with the drawing on it) down until the black background becomes the desired purple.

    :eek: Did you miss the part where he said it was too complicated for the Magic Wand?

    With linework, anti-aliasing (soft edges) is a definite disadvantage. Make sure you have a nice, high resolution scan and then go:

    Image -> Adjustments -> Threshold and drop out and soft edges.


    Select -> Color Range and use the eye dropper to pick up the black. You now have all the linework selected.

    Layer -> New -> Layer via Cut

    Your linework is now selected and is on a layer of its own. Either use the selection or lock transparency on the layer and fill with the colour of your choice.

    Fill the previous layer with your preferred background colour.

    Job done.
