Spotify : Consistent use of green, the typeface and the logo across websites, flyers and gift cards makes the spotify one of the good Identity systems. Also the object edge curves and shapes are consistent across different print and web materials. what I like about spotify is the color and typeface used which makes it unique. Also the way green is used makes one associate this shade of green with spotify.
iVOMAT: iVOMAT uses white and greenish yellow across all the print and web materials. Arrow shape that separates theses two colors makes a unique shape that is used consistently by iVOMAT. This arrow looking shape is used even in the letterhead footer and logo. What I liked the most is use of the shape across the different forms. Also the shape is used in different ways like in log and in footer in different sizes yet maintaining the ratio and color combination which makes it unique.
Apple: Apple uses the custom typeface which is used across different products. And this typeface uses the particular gray hue which adds to the uniqueness. The gray shade is even used in hardware like macbook and iPad. the apps i iOS uses a particular curvature and it is the same in dialogue boxes, apps and even iphone edges. What I like the most about apple identity system is the consistency across their products including hardware. Also the use of typeface across different platforms lke iOS and iCloud and iTunes.
Apartment therapy: Apartment therapy uses different color across different media. Orange logo and blue letter on business card. The typeface used in logo is different from that of letterhead. The main design aspect for an identity system is consistency and which was missing in this. Also I did not like the way typeface is used as it is different in different places. even the shape and corners visiting card does not match with the website.
Southern Comfort : It uses different typeface and color combination for the same product which makes identity system a fail. Southern Comfort uses white background and red font and sometime the colors are interchanged on same product. The outline around the text exists on some labels and absent on others. As shown in the picture the fire symbol is used in all angles possible; which makes not so unique about the image. Also this design lacks repetition and consistency.
