Hola,
Very good image. I have taken a look at it on 2 different PCs with different Monitors and the main problem is that the creator of the image has also a very different Monitor then we do and this is a global problem when presenting images on the WWW.
Some have calibrated monitors, some like the very white which really is a bluish tone, other like a warm adjutment, etc. etc. etc. I work in the Textile industry and in order that the housewives see the white clothing whiter is that we add some blue dye into the washing products and so the white looks whiter :-) Optical ilusion.
The other problem is some people do convert!, never assign a colour profile for presenting an image on the WWW, the images to be presented to sRGB as it should be, because not all Browsers can present correctly the images with other colour profiles.
I think this topic has been discussed already many times in many imaging forums and belongs to the topic Colour Management.
So what do I want to say ? The best is always to convert the images to be presented to sRGB profile which every Browser understands and if possible, if you do not calibrate your monitor at least once a month with a spyder, to use the sRGB or 6500K setting which nowadays is possible with every LCD or LED monitor.
All I wrote surely is known by most of the forum members here.
