RAL Colour 1013
This RAL 1013 Colour is presented to you as a part of yellow 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 yellow colours are sequentialy coded under 1xxxx, where 1 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 Oyster white 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 'oyster white', you will find hand-picked colour tones selected by RAL institute design experts. This yellow colour assortment holds another 49 excellent tones (making a total of 50 unique colour samples).

◾ RAL 1013 to CMYK
In the CMYK colour system the RAL 1013 is composed by combining four primary tones of pigment. To achieve this exclusive "oyster white" colour tone, out of 100% maximum colour components, 5% cyan, 10% magenta, 20% yellow and none 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 1013 to RGB
The conversion of RAL 1013 into RGB colour space requres specific composition of red, green, and blue primary colours.
To construct hue matching "oyster white" colour from the RAL chart as close as possible, we use the following values ranging from 0 to 255 on the RGB colour system: 227 red, 217 green and 198 blue.
The three circle RGB diagram here provides illustrative example showing how red value stands out just slightly in comparison to green and blue to construct this light tint of colour. The RAL colour equivalent emerges in the very center, where all three primary colour circles overlap and combine.
