Transparent color

I am new to Photoshop and starting with Photoshop 6. With this new Save for Web, How do you select a color to be transparent when saving as a Gif?. Sorry if it is quite basic but I can't find a way of doing it as in previous versions.

raimundo,
The Save For Web Command was introduced in Photoshop 5.5, an upgrade which mostly appealed to those interested in designing for the web. It functions much the same in 6.0. If you want a graphic to have transparent areas, put your graphic on a layer above the background and hide the background layer (click "off" its little eyeball icon so you're seeing the gray/white checkerboard.) When you choose File: Save for Web..., Gif should automatically be the format and the Transparency Box should automatically be checked (in 5.5, you have to check it yourself.)



If you want to choose a matte color to blend transparent pixels against, so the edges of your graphic look better you can choose white, black, use the eyedropper to specify a color from the image, or click Other... choose a color from the Picker.
