Excercise - Primary and secondary colours

There are so many colour in nature especially in authumn when all the leaves change colour.
But to find certain colour dominant in an image, it is more difficult. The primary and secondary colour I could think of that occur in nature is colour of trees, grass, flowers, fruits, vegetable, rocks, sky etc
even sky has different colour depending on time of the day.

Primary colour:- Yellow, Red, Blue

Yellow:
At the time of this homework, it's authumn and there is no flower left. The leaves are changing colour but there is no yellow dominant in them. So I could only think of lemon.
And market stalls are great place to find colour.
This image was taken at one market stall in Croydon. I did took a few of lemon from different stalls but I like this one below the most because they stack on top of each other.

I took this image from one of the market stalls as well. The colour of these tomatoes are so vibrant.

Secondary colour:- Orange, Violet, Green

Orange:
This image below also was taken at one of the market stalls. I could have taken photos of pumpkin because it's Halloween season but I like this image more because of thos cut in half orange.

Violet:
I didn't think I could find violet at all. I thought all the flowers would have gone by now but luckily I found these flowers in Beddington park one morning. I zoomed in close so the colour could fill the frame. Even though there is some yellow but I think the violet is more dominant in the image.

-1/2 stop darker


Green:
The leaves are changing colour but not the one below, yet. I like how the green is not too dark and when it's lit by the morning light, it looks even lighter.

+1/2 stop brighter


-1/2 stop darker


Summary:
The -1/2 darker makes the colour look deeper while the +1/2 brighter tend to wash the colour out.
Some of the images look better with darker such as sky but some look better, in my opinion, with the camera meter reading as is.
