    Don't look like dust to me. More like noise. What was the ISO setting and shutter speed?

    yeah.. looks like noise.. noise is always more prominent on solid coloured surfaces.. so u'll notice it easily.. dust is more like big blur spots on the photo.. not speckles...

    Read these 2 links:

    Noise Part 1
    Noise Part 2

    You'll then understand how come some noise is multi-coloured....

    Its noise. It happens when you take long exposure shots without NR (Noise Reduction) turned on. NR is on the second page of the first item on the menu panel.
