In Mac OS, choose Photoshop > Preferences > Interface. In Windows, choose Edit > Preferences > Interface.There is also an option that allows channels to be represented in color if you prefer. Grayscale images are the standard representation of channels. Paint with black to remove the channel’s color. Paint with a value of grey to add the channel’s color at a lower intensity. Paint with white to add the selected channel’s color at 100% intensity. You can paint on only one channel at a time. To edit a channel, select it and then use a painting or editing tool to paint in the image.Shift-click to select (or deselect) more channels. To select a channel, click the channel name.If we convert our image to a CMYK color mode, our channels palette is now represented by four channels instead of three like the RGB color mode.Īn image in grayscale color mode would then only have one channel.Ĭhannels can be Select and edited following these procedures: This is because the image is composed mostly of this fantastic blue sky reflected on the water. The brighter areas of the color channel represent areas that contain more color and the darker areas represent less color.įor instance, in this particular image, the Blue channel is lighter than that Green or the Red channels. The color channels palette window in Photoshop can be found in Window> ChannelsĮach color in the color mode is now represented by a color channel represented by a grayscale image. It is represented by percentage values and is associated with printer inks. It is obtained by combining the colors Cyan, Magenta, Yellow and Key (Black) in different amounts. The CMYK color mode is a subtractive process. This mode is associated with digital displays such as monitors, digital cameras and scanners. It is obtained by combining the colors red, green and blue in different amounts represented by values from 0 to 255. The RGB color mode is the additive process. The RGB and CMYK color modes are the most used ones. There are a few color modes that can be used in Photoshop like the Grayscale, Index, Lab or Multichannel. It is a result of thousands of years of human evolution and adaptation to the environment. After processing the number of activated cones and the strength of the signal, this allows the viewer to see color. The light reflected by a yellow object in daylight conditions stimulates the red and green cones. Cones contain color detecting molecules with red, green and blue photopigments.

Two different types of cells inside our eyes are responsible for this process: rods and cones.ĭarker environments stimulate rods. It is estimated that we are able to distinguish up to 10 million colors. The visible spectrum for humans is between ultraviolet light and red light, in a wavelength between 400 and 700 nanometers. To understand how a color channel works, it is important to understand the relationship between light, color and the way our eyes see it.
