I'm currently working on a still life and I'm having trouble getting the correct colors/values. I like to use natural light in my compositions and take pictures which I then use as my reference. I've set up my studio with neutral lighting (5,000 k) and pull up the reference on a photo editing software to work from as I paint. While I'm painting in the studio lighting, the colors seem to match perfectly. I even use the eyedropper tool to check colors at times. However, when I take the painting out of my studio area or try to take a picture of my painting with my phone to compare to the original, the colors are all off!
Any idea of what I'm doing wrong here? I know ideally I should be painting from life in consistent lighting, but that's not always practical for me.
Thanks in advance for any feedback!
