The contrast ratio of the background and text should be at least 3:1.Strong colours should be used economically, i.e. only to highlight important information.11.6 IconsMost common icons can be divided into Application icons, List icons and Note icons.There are also several indications of different sizes and small icons in the UI, which are defined by the application.Small list icons should be kept very simple and two dimensional. Application icons and note icons can be threedimensional and more detailed.The metaphors are usually taken from everyday situations, mostly from the office environment. The metaphors shouldbe globally relevant, not offensive or ambiguous (see also chapter 13).In all icons, the light comes from the upper left-hand corner. The shadows are on the bottom right and behind theobject. The viewing angle of the objects in icons is from the front top left or right (and in small list icons, directly fromthe front).11.6.1 Icon paletteIcons have their own 35-colour palette, which should be used when a new icon is created. The colours are pure andbright to bring ‘‘spice ‘‘ and fun to the UI.Colour RGB1 White 240,240,2402 Grey1 48,48,483 Grey2 80,80,804 Grey3 96,96,965 Grey4 128,128,1286 Grey5 160,160,1607 Grey6 176,176,1768 Grey7 192,192,1929 Grey8 208,208,20810 Grey9 224,224,22411 Black 0,0,012 Light yellow 240,240,9613 Yellow 240,240,014 Light orange 240,224,14415 Orange 240,160,016 Beige 224,176,11217 Brown 192,112,3218 Reddish brown 160,48,019 Dark brown 112,48,1620 Red 240,0,021 Pink 240,48,11222 Light pink 240,176,19223 Smoke (greyish blue) 96,128,17624 Light blue 192,224,240
