I wish I could just open a virtual classroom, so that we could talk about these things. Tarek I don't quite understand your question, is it in photoshop you are trying to understand these things? One great resource is the site http://www.huevaluechroma.com and also see http://www.cambridgeincolour.com.

I'd be happy to to talk with you, but don't have any readily available materials in english. If only there was a way to book a live Connect room in the education exchange.

I am very interested in learning more about "blend modes" and "color space" and the impact on the visual experience. Where can I find more information on using color?

Opacity is the opposite of transparency. An opaque object is not transparent but covers completely. This answer needs to be modified since transparency blend modes synthesize a new colour depending on the colours and how they are blended. One important thing to note is that the colour space affects how colours are blended. It is easier and more predictable to. Blend RGB images since any given colour only has one set of values (not so in CMYK).

I would be happy to talk more on this, please explain more closely what you want to know.

i want to understand the software calculation if we blend 2 colors; top color will be 50% opacity?

Depends on many factors, the colour space (RGB or CMYK) have a great impact as do blend modes.
