yellow or both colors?
In the quest to find out if there's any hidden meaning/psychology behind it
I found a few interesting things relating to graphic/packaging design.
So next time you make a beeline for that Big Mac, bare in mind that colour
has direct physiological effect on the brain. Red increases pulse, blood
pressure, and respiration (stimulating appetite) while yellow is the easiest
colors that can be seen from the longest distance.
Interesting, if not a tad worrying that the exact same colours are commonly
used in warning signs.
Looks like designers need to be psychologists too...
Below a bit of an extract from something I found on the web
Consumer Psychology - Colour
³Reds, oranges, violets, and true greens stimulate hunger. These colors are
on the majority of packaging. How the colour is distributed on the
package<for example, 15% to 20% purple, 70% to 75% gold, and a 5% splash of
red<can also stimulate appetite.
Red and yellow, the trademark colors of fast food, encourage eating quickly
and quick table turnover. Yellow (happy and warm) and red (stimulating and
speed) are probably the most popular colors used on snack food packaging.
Red, however, also indicates danger<of eating too much, too quickly, and too
often.
Colour identifies flavour and edibility. The exception is blue. Though blue
conveys trust, reliability, belonging, and coolness and appears on some food
packaging, few foods are really blue. Blue can suppress the appetite.²
So its Pepsi and Cheese and Onion flavour crips all the way for all those
dieters out there then!
Have a look at how many fast food restaurants have their logos in the
strong, attention getting contrast of red and yellow or any of the two
colors.
