先日、北海道カラーユニバーサルデザイン機構（北海道CUDO）のイベントで、「色覚体験ルーム」というのを経験した。特殊な分光特性を持つライトに特殊な光学フィルタを被せたものを照明として使用しているその部屋の中では、一般型の色覚の人でも、P型（1型）やD型（2型）色覚の人と同様に色が見えてしまうのだ。つまり、特定の色の組合せにおいて、色の区別がつかなくなってしまう。こんなすごいものをよく作れたと思う。その部屋の中でいろいろなものを見たが、裸眼で色覚体験を行うのは、シミュレータを使ってディスプレイ上で見るのとはまた違った臨場感がある。貴重な体験だった。

Golden Ratio in logo designs
Apple is probably the only company not to use its name in its logo. Despite that, the Apple logo is one of the most recognized corporate symbols in the world.
What’s the secret?
Some of company’s logo artists have infused its logo with some mathematical elegance, with the Golden Ratio or φ.
The golden ratio has been around since at least Euclid and Pythagoras. Fans of the Da Vinci Code should know it too, as Dan Brown has referenced φ several times in his books.
Golden Mean, Golden Section, Divine Proportion are all common names for what is known as the Golden Ratio which is based off the number phi (φ) = 1.61803398874… discovered by Italian Mathematician Fibonacci. Phi (φ) is the ratio between the number sequence 1, 1, 2, 3, 5, 8, 13, 21 etc. where the next number in the sequence is derived by adding 2 numbers together. So, 1+1 = 2, and 1+2 = 3, 2+3 = 5 and so on. When we divide two sequential numbers i.e. 5/3 = 1.67 and 21/13 = 1.615 the ratio between these numbers soon become very close to φ (1.618).
What’s so amazing about this number?
Some believe that it is the most efficient outcome, the result of natural forces. Some believe it is a universal constant of design, the signature of God. Whatever you believe, the pervasive appearance of φ in all we see and experience creates a sense of balance, harmony and beauty in the design of all we find in nature.
No wonder the logos, which are made of this procedure seem so elegant and aesthetically pleasing.
Beside the Apple and iCloud logo, inter alia National Geographic’s, Pepsi’s, BP’s and Toyota’s logo also made with using Golden Ratio.
私は自分に自信がなくて、人より友だちは少ないと思うし、みんなでいるときとか、私がいてもいなくても何も変わらないんじゃないかなって思うことも多くて。でも、会いたいって言ってくれたりする人がいて、泣きそうになる。自分が想像しているよりも、ちょっとだけ、私、好かれてるのかも(笑)とか、昼下がりに思った。
