But how is it even possible for us to be tempted to think that we use a word to mean at one time the colour known to everyone--and at another the 'visual impression' which I am getting now? How can there be so much as a temptation here?--I don't turn the same kind of attention on the colour in the two cases.  When I mean the colour impression that (as I should like to say) belongs to me alone I immerse myself in the colour--rather like when I 'cannot get my fill of a colour.'  hence it is easier to produce this experience when one is looking at a bright colour, or at an impressive colour-scheme.
