Why is it so hard to recreate the colors of Tuscany while painting?

The light in Tuscany is so brilliant and natural. It shines on the beautiful houses and water in such an amazing way that it’s almost impossible to realistically recreate such a spectacle. Though the colors are widespread, they are very specific and hard to match.

You do not mention your medium or what techniques you have tried so I will
give a general answer which may help.

While it is true that the beauty is impossible to truly capture on canvas there may be
some basic steps blocking you from the best recreation possible.

Painting light is as dependent on you pigments as it is your skill.

To achieve light you need to use pure pigments rather than hues. Pure pigments are the colors milled from the natural source. They are more expensive
because they require only the source from which they were traditionally derived.

Hues are less expensive- Most student and much mid-grade paint are hues. They look the same as the pure pigments on palette however they are created by mixing different colors from different sources and will usually react much differently when mixing and will easily muddy.

I would venture a guess that even the best painter could not capture the incredible glory and light of Italy with hues.

Also be sure you are using a solvent that does not cause pigments to cloud. Read the label- you may be surprised.

Since I am not there with you and do not know what you have already tried nor the vista that you are actually trying to capture it is hard to suggest techniques. I wish I was!
I sometimes use a ground of lead white which I let dry then use transparent pigments to glaze in color when looking to paint light however others have different techniques.

Acrylics, golden.

It has been a long time since I used acrylics but when I did I recall preferring the tranparent colors. Perhaps an acrylic landscape painter will make suggestions.

Another thought- the illusion of luminescence is dependent on contrast of light and dark. You might be sure you have enough dark to make the light pop.

Another thing to remember is that in nature there is no such thing as a “green” anything. Every single green is multiple as the foliage or grasses turn in the light and vary from young to older and cast shadows and highlights….
you cannot paint a “green” tree without using a big variety of greens. This is why green hospital walls look so dead. In nature (which is good for us biophiliac animals) we bond to this extreme variability in greens, and a flat green makes us know it’s not “real”, which makes us a little sick.

In the clear Tuscan light, there’s no mediating haze. So the colors are even clearer than in many other places. Yours must be the same. Thus, as dog says, your paint must be of the highest possible quality, and your painting medium clear rather than, say, yellowish. And keep your brushes clean, girl!
If you’re a girl.
