7 How many colors can you have in a GIF image?

Answer 1

GIF format supports up to 8 bits per pixel, allowing a single image to reference a palette of up to 256 distinct colors chosen from the 24-bit RGB color space.

JPEG files embed an ICC color profile (color space). Commonly used color profiles include sRGB and Adobe RGB which are often 24 bit (16.7 million colors). ^{255 255*255*255}

Answer 2

Only one.

There is no format known to me that supports more than 1 transparent color / single image. I cannot imagine the use for multiple transparent colors without having multiple layers in the image. Do not confuse the transparent color (which is 100% transparent) with transparency in general. You can overlay an image using transparency (e.g. 50%) and having a transparent color. The result is that all image pixels having the transparent color will be replaced by the background image, while the others will retain in 50% ratio their color.
