Hi Ruben,
The reason for this "blue" is the tone mapping settings, specifically the white balance value.
I would recommend resetting it, you can see the button for it next to "+" in the tone mapping.
Afterwards, try lowering/increasing the Exposure value, you shall get better results.
By the way, it seems that you are doing a product rendering, but outside, under clear sky. This won't give the "best" results for product rendering.
Try removing the environment map, and use CoronaLight to light up the scene. Create a few of them, change their color, intensity, until you get the look you want.
Some "base" - a plane, table etc. - for the product will also be good.
Hope this helps.
A big hug back to you too!
