RGB is specifially suited to computer screens or televisions, it is not for printing.
In Photoshop you can not convert RGB to Dulux.
Open image. At top of screen, click IMAGE>MODE>RGB.
RGB is color mode suitable for on screen viewing, rgb layer means that layer is in rgb color space. IN Photoshop you can see (or change) in which color mode you are working from Image > Mode
RGB is color model and is suitable for screen. All colors in RGB are made from 3 primary colors Red, Green and Blue. There are also other color models like CMYK which is suitable for print. You can convert RGB to CMYK and vice versa in Photoshop.
Hi all, The RGB stands for the RED GREEN BLUE as the standard color code format in the photoshop.If u select this option then u can view the photo is the respctive color.Also u can increase the color contrast format.
If you read that somewhere and want to know what that means: That means the default setting for photoshop before any color customization. The advanced one takes in account your destination color space (printer, separation, screens) your dislplay's color space, and several options for managing a missing or embedded profile scenario. You can't use a system set like that for pre-press. Just for RGB images to be displayed in a PC screen, and you should not trust in that RGB source for color separations. The web design rendering is based in the RGB standard for monitors and screens (home ones, not expensive or precise ones) sRGB IEC61966-2.1
Color mode is color space you are working in, determines which colors u can use and number of possible colors. RGB is suitable for screens, and by the way use this color mode for your work inside Photoshop.

I bet you have your default format set to bitmap or black and white. The format must be either RGB or CMYK.
Probably because you work in Grayscale mode. Go to Image > Mode and click RGB Color.
Set image properties (quality or mode) to RGB.
The underlying color model in Photoshop is neither RGB nor CMYK but LAB. It has the widest gamut, which means it can hold more color values than any other model. Of the two other models, RGB has more color values than CMYK does. When you convert from RGB to CMYK, the program first "maps" the RGB values into the LAB colorspace. It then maps the LAB values into the CMYK colorspace. Now, for REAL entertainment...take a pure RGB blue, or a pure RGB green, and attempt to map it into CMYK colorspace. It doesn't work at all. Red maps fine, but the other two go straight to hell.
