Weekday colours (Ayurveda)

Published by Peter on August 21, 2007 in color. 4 Comments

My girlfriend recently introduced me to the fact that the days of the week have associated colours, and that one might take these into account when choosing what to wear, to eat or  -in my case- what to drink. The colours are defined by the Ayurveda, the “ancient system of health care that is native to the Indian subcontinent“.

Since I always forget what colour of underwear to put on on which days, I’ll write it down here:
ayurveda colors

Monday: Lord Shiva rules on Mondays. White is the colour for Mondays and therefore wearing white dresses and keeping white flowers at home are recommended on Mondays. It is a good day for men seeking favours from women and for making new friends. Taking honey and cucumber on Mondays is likely to yield good results.

Shades of purple

Published by Peter on February 2, 2007 in color. 5 Comments

Have you ever gotten into a discussion with a woman on colours? It seems that, while some people have ‘absolute hearing’ (pinpoint any frequency to the right note), there is also a kind of ‘absolute colour perception’, and women seem more often blessed with it. While us men have the habit of calling anything with a red/blue mix ‘purple’, life is actually not that simple. There is violet, mauve, orchid and half a dozen variations on those.

To make things even more difficult for Belgian men: we actually have two words in Dutch: ‘paars’ is the equivalent of ‘purple’ in English, while ‘purper’ is more like magenta. Ask any man here (that’s not a fashion designer or hairdresser) the difference between ‘purper’ and ‘paars’ and you’ll get utter astonishment.

So here’s a reference chart of purples:

If any woman/color-sensitive man would like to point out more variations of purple-ish colours, be my guest!

Poor-man’s sepia conversion

Published by Peter on October 13, 2004 in color, photography and webdev. 4 Comments


Working for Pixagogo makes digital imagery my daily bread, and I fool around with images every now and then. I am, however, not a user of PhotoShop. I’ve never worked with it, I don’t own the software, nada. Keep that in mind while you continue reading this.

Recently, for my cousin’s filmfilostoverij blog, I converted some film snapshots into small thumbnails like the one on the right (from “Lucia y el sexo”). The program I use for conversion is IrfanView. Not the best program, not the most complete, but easy, stable and free. For the stuff I need to do, I find Gimp too complex.

What I did to the images was:

  1. crop a square part of it
  2. convert to grayscale
  3. resize to 400×400 px
  4. perform a median filter (value: 9)
  5. resize to 100×100 px
  6. Save as JPG

But then I wanted to have a ‘sepia‘ effect. Irfanview does not have it. I wanted it. So I began my quest.


I started with the ‘Enhance Colors’ function and added 64 ‘R’ and 16 ‘G’ to the B/W image, but that didn’t look real enough. What does sepia look like, anyway? I found two definitions, expressed in CMYK coordinates, that I converted to RGB with my CMYK-to-RGB converter hizmo (thanks to Wikipedia):

The color
1. \definecolor{Sepia}{cmyk}{0,0.83,1,0.70} (from TexCeh)
#4D0D00 (77,13,0)
2. sepia cmyk(0%, 60%, 81%, 63%) (from december.com)
#5E2612 (94,38,18)
In ‘websafe‘ colors, this would be:
#551100 (84,17,0)

So let me show you how I proceeded, using an image of my tango teachers, Marisa y Oliver:

original image
Original
  1. Convert to greyscale
  2. Enhance colors: 94-38-18 (#5E2612)

=> way too red!

  1. Convert to greyscale
  2. Enhance colors: 77-13-0 (#4D0D00)

=> color OK, but too light

  1. Convert to greyscale
  2. Enhance colors: 77-13-0 (#4D0D00)
  3. Add 50% contrast

=> looks great

    Compare this with the optional QuickSepia plugin

=> I like mine better

Voila, there it is, a simple poor-mans sepia, that can even be used in ‘batch convert’ (Irfanview).
