Cobalt blue

This RAL 5013 Colour is presented to you as a part of blue hues assortment on the RAL Classic colour chart. You will notice that all of these grouped colours follow this specific designation, which is based on four-digit number in combination with the letters "RAL". This is why blue colours are sequentialy coded under 5xxxx, where 5 is a system code number (1: yellow, 2: orange, 3: red, 4: purple, 5: blue, 6: green, 7: grey, 8: brown and 9: white and black shades).

The name Cobalt blue actually serves as additional, auxiliary designation, making the colour easier to remember. This naming system also provides additonal quality assurance preventing erroneous colour assigment due to number transposition.

The conversion of RAL 5013 into RGB colour space requres specific composition of red, green, and blue primary colours. To construct hue matching "cobalt blue" colour from the RAL chart as close as possible, we use the following values ranging from 0 to 255 on the RGB colour system: 25 red, 49 green and 83 blue.
The three circle RGB diagram here provides illustrative example showing how blue value stands out clearly in comparison to red and green to construct this unique tone of colour. The RAL colour equivalent emerges in the very center, where all three primary colour circles overlap and combine.
