There is no direct relationship between the mean and mode.
The mean. Or the mode.
There is not much point in calculating the mean or mode of a single number. The mean of 5 is 5. The mode of 4 is 4.
the median and mode are but the mean is not
The median is 9 and the mode is 18 and the mean is 11
You mean Color Mode? Changing how Photoshop treats and displays colors in an image.
Replacing and blending pixels at same time.
The easiest way is to right-click on the layer you wish to change (active layer) in the Layers panel, then select "Blending Options" at the top of the Menu. You can also select Blending Options from the "Create Layer Style" icon (FX) at the bottom of the Layers panel.
you can combine by creating masks or blending options,you need tutorial for doing such thing
To blend two layers in Photoshop, select the top layer, go to the Layer menu, choose Blending Options, and adjust the Blend If sliders under the Blending Options panel. You can also use blending modes like Overlay, Soft Light, or Multiply for different blending effects. Experiment with different settings to achieve the desired look.
In the color palette, there is a drop down option default normal option selected... Select and gotcha your blending options are displayed but I don't know about further options....
color layers is simply color layers
Probably because you work in Grayscale mode. Go to Image > Mode and click RGB Color.
you can do this under Image> Adjustments> Brightness/Contrast and pull the slider on the Brightness down. You may want to increase the contrast if needed. Duplicate the Background layer, then set the Blending Mode of that layer to Multiply. From there you can add a Layer Mask and paint away any areas that got too dark.
you can use this to mix two colors together like actual paint brushes would. its good for blending hair and soft edges.
Open image. At top of screen, click IMAGE>MODE>RGB.
3, Normal, Fullscreen with menu bar and Fullscreen mode.
