Hiroshima Peace Memorial Museum


I have visited to Hiroshima Peace Memorial Museum this morning. Notably, its description of the Nuclear Bomb experiences were characterized by many color terms.

Such as, blackish red-orange, grey, black rain or purple spots. Nonetheless our memories of visual information tend to be composed of color, each color represented pain.

2nd International Conference: Digital Culture & AudioVisual Challenges


On 10-11 May, I have attended 2nd International Conference: Digital Culture & AudioVisual Challenges, Interdisciplinary Creativity in Arts and Technology at Ionian University, Corfu, Greece.

I gave an oral presentation on the First Color Digital Art x Lighting Symposium and Workshop held at SIT in March.




Oral Presentation

This book used to be worth approximately 70,000 yen in 1954!


I just bought a used color chart: Color Dictionary, which indicates the price: 3,500 yen. The average starting salary in 1954 was around 10,000 yen. Thus 20 x 3,500 yen turns to be 70,000 yen. Still color charts are costly in nowadays.
