Started coloring the main subjects

It's been a while (about a month?) since I updated last time. But I came back to the stilllife. Now I started working on the main subjects, red onion and apples. If I were Michele Usibelli, I would put more highlighted colors at this early stage. But I didn't. I'm still not determined how warm, or cool, those colors should be. Even though my studio (basement) is cooler than the other rooms of my house, I started worrying about the fruits and vegetable that might get pale in color soon. I might replace them with fresh ones. It looks like the time for the lime now.That's the main reason I started detailing the subjects.
