RAL Colour 6015
This RAL 6015 Colour is presented to you as a part of green 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 green colours are sequentialy coded under 6xxxx, where 6 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 Black olive 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 'black olive', you will find hand-picked colour tones selected by RAL institute design experts. This green colour assortment holds another 35 excellent tones (making a total of 36 unique colour samples).

◾ RAL 6015 to CMYK
In the CMYK colour system the RAL 6015 is composed by combining four primary tones of pigment. To achieve this exclusive "black olive" colour tone, out of 100% maximum colour components, 25% cyan, 5% magenta, 30% yellow and 90% 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 6015 to RGB
The conversion of RAL 6015 into RGB colour space requres specific composition of red, green, and blue primary colours.
To construct hue matching "black olive" colour from the RAL chart as close as possible, we use the following values ranging from 0 to 255 on the RGB colour system: 61 red, 61 green and 54 blue.
The three circle RGB diagram here provides illustrative example showing how these relatively low values comes together and constructs such dark, yet unique shade of colour. The RAL colour equivalent emerges in the very center, where all three primary colour circles overlap and combine.
