Coloured weights

You have six weights. Two of them are red, two are blue, two are green. One weight of each colour is heavier than the other; the three heavy weights all weigh the same, and the three lighter weights also weigh the same.
Using a scale twice, can you split the weights into two sets by weight?

Not Roman numerals

The letters $$I$$, $$V$$ and $$X$$ each represent a different digit from 1 to 9. If
$$VI\times X=VVV,$$
what are $$I$$, $$V$$ and $$X$$?
