Hi

I picked these 2 colors named mix dark brown and magenta from color adobe's official website and then I placed those colors to my Adobe Photoshop CC 2015 to make them my website colors which I used on this website Japanese Knives Blog for the theme I selected from adobe colors as my primary color theme.

But when i put color codes into my website header and footer then both the colors changed to some other colors but i really dont know why this happened.

Is this possible that when we pick colors from one website then it changes to another website?

Edit your theme at color.adobe.com and make sure the Color Mode is set to RGB. When the Color Mode is RGB, the listed Hex and 0-255 RGB values are sRGB.

Your footer’s background-color is set to rgb(89, 2, 2). The same color at Adobe Color matches in appearance, here in Firefox:

If you are designing in Photoshop make sure your PS file is RGB with sRGB as the assigned profile (Edit>Assign Profile...)
