Transition elements, variable oxidation states and colours

Hi everyone, thanks for reading in advance :smile:

I'm busy preparing for my final high school exams fast approaching in November, and am desperately trying to patch up any holes in my chemistry knowledge before then.

One of these (unfortunately numerous) holes in my knowledge of chemistry in general is the coloured complexes that transition metals can form. I'm pretty steady on the concept of why the different colours form in the various transition element complexes, but I can't remember which colour applies to which oxidation state of which element.

I was wondering if anyone here might have a link to a site, or have a file saved on their computer, which contains a straight forward list of all the colours of the period 3 d-block elements in their different oxidation states? If I can just get a hold of a list of them all, I'm sure I can route learn them all in time...

This would really, really help, so if anyone could give me any information at all, I'd be supremely grateful.

Unfortunately for AQA you just have to 'know' the colours, states etc of by heart. There's no easy way to work it out, you just have to memorise everything.
