RAL Colour 5010
Gentian blue
This RAL 5010 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 Gentian 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.
On this particular hue range, in addition to 'gentian blue', you will find hand-picked colour tones selected by RAL institute design experts. This blue colour assortment holds another 24 excellent tones (making a total of 25 unique colour samples).

◾ RAL 5010 to CMYK
In the CMYK colour system the RAL 5010 is composed by combining four primary tones of pigment. To achieve this exclusive "gentian blue" colour tone, out of 100% maximum colour components, 100% cyan, 70% magenta, 5% yellow and 15% key (black) are used.
You can immediately see this result on this computer simulated CMYK diagram.
The mixture of these primary colours blends in the middle on a square space where all four different colour hue sheets overlap.
◾ RAL 5010 to RGB
The conversion of RAL 5010 into RGB colour space requres specific composition of red, green, and blue primary colours.
To construct hue matching "gentian 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: none of red, 79 green and 124 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.
