# Color Formats Any given color can be displayed in various formats. NPS Color Picker allows you to select from multiple formats to use the color in other applications. If the current color cannot be represented by the chosen format, the closest match is used and a warning is displayed. You can choose to show or hide the closest match by clicking View -> Show effective (solid) color. ## Automatic This format will choose the optimal CSS color format that supports the specified color. The most restrictive option is chosen – it goes in order of: named color, 3 digit HTML hex, 6 digit HTML hex, and RGBA. ## Named Color Finds the named color that is the closest match to the specified color. ## HTML The 6-digit hex representation of a color. For example, the color Red is #FF0000. ## HTML Compact Uses the 3-digit hex representation of a color if possible (such as #F00 for Red), or the 6-digit representation if not possible. ## CSS3 RGB(A) The CSS3-compliant RGB (Red, Green, Blue) representation of a color. Uses `rgb` if the color is opaque, or `rgba` if the color contains transparency. ## CSS3 HSL(A) The CSS3-compliant HSL (Hue, Saturation, Lightness) representation of a color. Uses `hsl` if the color is opaque, or `hsla` if the color contains transparency. ## CSS4 HWB The HWB (Hue, Whiteness, Blackness) representation of a color, based on the CSS4 draft. ## ARGB Displays the Alpha, Red, Green, and Blue components of a color with the "argb" label ## RGB Displays the Red, Green, and Blue components of a color with the "rgb" label ## RGB Triplets Displays the Red, Green, and Blue components of a color with no label ## CMY Displays the Cyan, Magenta, and Yellow components of a color with the "cmy" label ## CMYK Displays the Cyan, Magenta, Yellow, and Black ("Key") components of a color with the "cmyk" label.
