thank you all for your replies they are very welcome, when I was taking the picture was taken it started to rain so had no tripod or time to check focus. the gear I use is Canon 80D with a 100MM L macro lens.
That is a decent setup, so your problem (IMO) either 1 of 3 things (or all of them):
1) You don't have your camera color set up to Adobe RGB, it's probably set at the factory sRGB;
2) You're shooting straight to .jpg rather than RAW, for post-processing; and/or
3) You were shooting at a really high ISO.
I would venture to say one or all of these factors were at play.
The Canon 80D has one of the better high-ISO capabilities, at least with Canon cameras, but like most crop-Canons it doesn't have the best color potential. Check out SenScore for more details.
A score of 1000 is considered A+ by current standards. 900 = A-, etc.
After you go to the SenScore then click > Scores > APS-C Cameras to see where its predecessor, the 70D, ranks. (They haven't yet tested the 80D.)
You will note the Canon 70D only has 166 color potential compared to the better FF cameras, which rank 1000+ ... thus it is only able to register a minimal amount of the total color potential in each given shot.
The 70D's noise handling is better, but still sub-average at 419. I expect your 80D is better than the 70D, but doubt it's much higher than 500-600.
I shot the similar 7D for many years (which scores even lower than your camera),and would never go over ISO 320-640, without seeing artifacts/noise. I had the 100L also, and it was a good lens for hand-holding, and getting quick AF shots, but it was terrible for critical manual-focus work.
I was able to get a lot of really nice images with this combo, even with its dismal ranking, but only if I operated within a very limited set of ISO parameters, and only within a set of basic color potentials (i.e., un-complex backgounds, etc.)
