...




Black doesn't reflect light
and white..
white reflects all colours
But when you generate both on a computer screen
black and white are exactly the same color
...one is just brighter than the other.

Ah, so much truth right there...


I like it that you didn't say which one was brighter...

My podcast is up. Check it out here...

Random Magus said...

the domestic minx: Sometimes its pretty difficult to tell

Danielle: Cool.. I'll check it out!

meleah rebeccah said...

I totally agree with Minx.

and ... I really LOVE that photograph.

Bowrag said...

Arg,. Im so confused. I look at that picture and my head spins.

HollyGL said...

Really cool post, Random. Love that picture!

JYankee said...

That is really cool. Random, you really come up with some unique and little-known facts.

Zakman said...

hmmmm.... also, on a computer they cease to be colors... they become plain RGB codes

QUASAR9 said...

lol Random, hreat ditty!
I guess it's down to which background we use, difficult to see white on white, and not so easy to see black in the space at night

Random Magus said...

meleah rebeccah: It's called illuson of opposites.

Bowrag:That was certainly not my intention though :)

HollyGL: Thanks a lot - I find colours and how we are able to see them really fascinating

Random Magus said...

JYankee:
I was thinking of opposites and how in opposites, one is just a presence of something and the other the absence of it. Black and white seemed good vehicles

Zakman:
In computer graphics, a combination of just three lights is used to produce the colors on a screen, red, green, and blue [RGB]. Different systems for calculating colors are used. One of them is hue, saturation, and lightness. The hue of course is the color, eg red, brown, white, etc. The saturation is how much
of the other colors are present, and the lightness is how bright the color is. White and black have the same hue and saturation, the lightness is all that is different.


QUASAR9:
It's the background that gives most things context isn't it?

Oh my so true..n so well said..really almost like what i was trying..:)

m so impressed by your observance amber..it always captivate my thoughts..gr888

Random Magus said...

... thank you!

Nathalie said...

never thought about it that way...

Mark said...

Very interesting!

Random Magus said...

Nathalie and Mark: It is isn't it. All opposites just mean that one is the absence of other

Jeff said...

Do you ever wonder if we see the same things when we see colors? I mean my blue may look like your gold. We just see them consistently so we can talk about them. I don't know. I guess I am just starting trouble. :)

Dream Catcher said...

opposites just mean that one is the absence of other

very well picked amber..absolutely what i meant..:)

Jean-Luc Picard said...

I agree; good picture.

QUASAR9 said...

Random,
I just know you'll love this one:
King Arthur and the Witch

Random Magus said...

Jeff: I have always thought about this in fact in my 'mirror mirror' post I theorized about this.
Imagine if everyone saw you differently and if they started seeing you differently after they got to know you as well. Maybe some years down the road there'll be research on this and we would get to read about it one of Quasar9's blogs!

Dream Catcher: Thanks

Jean Luc Picard: Thanks - the picture isn't mine though [you do mean the picture on the post right?]

Quasar9: I totally did ;)

Ricardo said...

Yes, technology has it's own little tricks for replicating colour. There's also a deeper meaning to all of this and I will put my finger on it soon enough.

Random Magus said...

The meaning is what inspired this post

Titania Starlight said...

That pic sure caught my eye! You choose really nice pics for your post. I am very visual also. :o)

I love those comment thingies.

Random Magus said...

Titania:
I know your blog is a visual delight, you put in so much effort and it turns out looking really pretty.
I stole the comment thingies from your blog ;)
Hope you don't mind!
