8 down: Colour of sun on gardens (4). I have S_E_. I think "SKEW" s=sun and Kew (Gardens). But has skew anything to do with colour? Perhaps to colour ones judgement? Or am I way off beam here?
12 across: Instructions for PC might be easier to do on PC (9,5). I have "oper ations" for first word. But not sure about second word. I have _O_E_. Again, not sure why.
