Re: blue not purple

Yes, both answers are correct. Purple and some shades of magenta are always a problem.

I find that for the best results you need to avoid direct sunlight, which creates false colours (at least to our eyes) and always do a Custom White Balance. Cameras vary slightly so consult your instruction book. It does take a few minutes to set up each time but you soon get used to the 'ritual' and the setting often stays unchanged until there is a variation in natural light levels. It is the only way to get consistent results.

If you don't have a correct 'grey card' a sheet of very slightly off white paper will do for most purposes. Some people use the white card from the inside of a jar of instant coffee and I have even managed quite well with an old and slightly grubby white handkerchief.

Also shooting RAW will help as it gives you a chance to alter the colour balance/colour temperature during conversion. I find that increasing colour temperature by around 1000 degrees often helps.

Finally there is colour correction with your software. If the Colour Balance tool isn't working well enough I have found that using the Selective Colour tool and tweaking the Neutrals often helps. But I don't know the level of your editing expertise so I might be 'running a bit too fast now'
