If you want to get better pictures of the actual colors with your phone, I recommend using gel filters. I got mine on eBay and it makes my life so much easier. No apps to install, no post processing to do, etc. Below is a picture with a gel in the center to show the difference and also the ebay link.
Just play with all the orange filters and you will find one that makes everything look just like it does in real life.
I also use those clip on or magnetic rather, lenses that you get on eBay and they are pretty good. I rarely take out my Nikon these days. Below, I also shared a few pics I took with the macro lens and the gel filters.
Good luck.
