Rythm - Usage of Repetition

Posted by Jen in design & art, random thoughts on February 14th, 2009

pattern_cardRepetition with a certain amount of spaces creates rhythm in graphic design, due to the fact that repetition makes a pattern of consistency in the form of identical graphic elements including shape, style and color.  This design technique is very effective to unify and organize the entire creative piece, showing a clear flow in the design message and creating the sense and atmosphere of the graphic work.

However, too much repetition with too much identical elements can make the design to dull and too predictable to be stylish and appealing.  Repetition doesn’t necessarily to be copying elements exactly the same.   Variation can be a supporting and very important technique for repetition.  It can be variation in shape, size, position, color, etc, with which designers are able to create not only regular rhythm (repetition of identical elements), but also flowing rhythm (natural looking of movement) and progressive rhythm (a sequence of form to show the progression).  Space is also a very important factor supporting repetition to make great designs. The well adjusted space in between each repeated elements can create a sense of rhythm.  And again, they don’t have to the same amount of space, but rather spaces in the form of flowing as well as progressive rhythm.

Environment Design - Wayfinding in IKEA

Posted by Jen in design & art, random thoughts on February 12th, 2009

I like IKEA for its simple, neat and contemporary design style. Its style is not only represented by its furniture in store but also reflected by its branding. The wayfinding signs are just part of it.

The pictures were taken from IKEA at East Palo Alto. Driving through 101, you can see the big IKEA store sign from distance. With 4 capital letters in yellow and blue for the background, the sign is simple, but very outstanding-looking. Blue and yellow are the two primary colors for the store’s branding. At athe entrance of the parking lot, the sign of welcome and entrance are big and clear enough. Fonts are also san-serif, the same as the store logo, which is very legible. Inside the store, the wayfinding signs mostly consists two colors ñ deep blue as the background and white as the font color. For the arrow, it is always a circle white background with a big black arrow inside. There is a daycare center in store. The designer used foot print in yellow color pointing the direction and location to the place. This is an interesting design when it comes to things about the kids.

Overall, the wayfinding design in IKEA is consistent in its color, font, and the way the arrow is presented. For the kids place, they used a different style, but still the main design color ñ yellow, which made that place more kid-oriented. A very good design.
