RGB

RGB (Red, Green, Blue) is a popular method for defining colors.

RGB is comprised of three numbers representing the amount of red, green and red in the color.

For 24-bit colors, each colour component is defined by 8-bits and therefore their values range from 0 to 255.

8-bit numbers like to be represented in hexadecimal as two digits which also include the characters A to F. Combining all 3 colors, we get a 6 character hexadecimal value that is commonly used to describe color in html and many other applications. To indicate a hexadecimal color value in html, it begins with a '#' character.

The currently measured RGB color from the camera is shown to the right of the camera preview as decimal R, G and B values and with a box showing the hexadecimal color. Long tapping on the color box will copy its value to to the clipboard.

Tapping grab will copy the current camera color to the lower part of the screen making it available for tweaking and storing. The RGB value displayed at the bottom of the screen shows this grabbed/tweaked color. Long tap on this RGB box to copy its contents to the clipboard ready for pasting into another application.

Suggest Mode

The first of the 3 modes for the main display, shows the currently grabbed color in the center circle, and 6 smaller circles showing the closest html named colors from a list of 138 colors. Tapping on one of the suggested outer circles will grab that color and place it into the center circle. Tapping the center circle will just make that circle bigger and hide the smaller circles.

Adjust Mode

The second of the three modes for the main display, allows each or the Red, Green and Blue components to be adjusted, either by dragging the corresponding cursors around the arcs, or by tapping on the +1 or -1 buttons for that color. As the RGB values change, the effect of adding more or less of each colour is shown in the colored arcs.

List Mode

The third of the three modes for the main display, shows a list of upto 250 stored colors. The currently selected list item is highlighted in blue.

To change the currently selected item, just tap on a new one. Selecting another item will also grab that color making it available in the other modes if required.

To scroll the list, just touch and drag up or down.

To change an item position in the list, long tap on the item and then drag it to its new position.
