Brown grey

This RAL 7013 Colour is presented to you as a part of grey 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 grey colours are sequentialy coded under 7xxxx, where 7 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 Brown grey 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 'brown grey', you will find hand-picked colour tones selected by RAL institute design experts. This grey colour assortment holds another 37 excellent tones (making a total of 38 unique colour samples).

◾ RAL 7013 to RGB

The conversion of RAL 7013 into RGB colour space requres specific composition of red, green, and blue primary colours. To construct hue matching "brown grey" colour from the RAL chart as close as possible, we use the following values ranging from 0 to 255 on the RGB colour system: 87 red, 80 green and 68 blue.
The three circle RGB diagram here provides illustrative example showing how red value stands out just enough in comparison to green and blue 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.
