Recolor Images in PowerPoint

One of PowerPoint's most well hidden secrets is its ability to recolor images. Of course you can recolor vector clip art, but PowerPoint does have the ability to recolor bitmap images as well. That ability was never exposed in PowerPoint, but it's something you can use in Publisher. What deserves mention here is the fact that both PowerPoint and Publisher use the same OfficeArt engine as do most of the other Microsoft Office applications.
We'll explore two ways to recolor images in PowerPoint. The first procedure does everything within PowerPoint but is limited to recoloring images that are part of the background in a slide master. The second procedure uses copy and paste between Publisher and PowerPoint to recolor all sorts of images.
There's one thing you need to be aware of: by recoloring, I mean creating "duotone style" two color images like black and white, red and white, blue and white, etc. These are not pure duotones. For all practical purposes, PowerPoint converts a color image to grayscale and changes the mapped black values to another pure color.
I want to thank Howard Cooperstein, Lead Program Manager of the Graphics Product Unit at Microsoft Corporation for all his help without which this page would not have been possible.
Recoloring Backgrounds in a Master
This tutorial uses PowerPoint 2003.
- Launch PowerPoint and opt to create a new presentation
using a design template. This will activate the Slide Design
template.
- This tutorial will only work if you select any of these
three pre-built slide design templates:
- Clouds
- Ocean
- Textured
I repeat - you need to choose any of the above templates since Microsoft exposed the image recoloring algorithm only in these templates. I chose the Textured template, but you could choose any of the three for the rest of this tutorial.
- Choose View | Master | Slide Master. In the Slide Master
view, choose Format | Background. You should be presented
with the Background dialog box. Click on the fill drop
down box and choose the Fill Effects option.
- In the resultant Fill Effects dialog box, select the
Picture tab and click the Select Picture button
and choose any other picture. Click Apply to All in
the successive dialog box. Choose View | Normal to get
back to the default editing view in PowerPoint.
- Choose Format | Slide Design and then choose Color
Schemes in the Slide Design task pane. Click on various
color schemes to view a duotone style background image
on the slide. The color of the resultant duotone style
background is directly related to the slide background
swatch of the active color scheme.
Recoloring PowerPoint Images in Publisher
PowerPoint 2003 and Publisher 2003 were used for this tutorial.
- This is a fairly simple process. Place all required images
on a PowerPoint slide and launch Publisher, where you should
create a blank print publication.
- Select the image in PowerPoint and choose Edit | Copy.
In Publisher, choose Edit | Paste. Since all Office applications
use the same art engine, it's almost the same as exchanging
content inside the same application.
In Publisher, right click the image and select Format Picture.
- In the Format Picture dialog box, select the Picture
tab and click the Recolor button.
- Click the Color drop down box, choose More Colors and
select the color you need.
- Copy the image (Ctrl+ C) from Publisher and paste it (Ctrl + V) inside the PowerPoint slide.
Note: You can achieve more consistent results if you note down the RGB values of the slide background color in PowerPoint (in Color Schemes) - and then use the same RGB values to colorize in Publisher.
