RGB Vases – P242 by Oscar Diaz



London Design Festival 09: Spanish designer Oscar Diaz has designed a set of red, green and blue vases that nest inside each other to appear a specific hue of purple.


The vases are hand-blown and will be exhibited as part of an exhibition called Eyes on Spanish Design at 100% Design in London in September.


Diaz also designed the Ink calendar in our previous story.

Here's some more information from Diaz:


Oscar Diaz Studio
RGB Vases - P242

Project Description:

The RGB vases combine the excellence of a process like glass blowing, refined through more than two thousand years, with references to the contemporary culture, were screens are extremely common, and its colors, based on the RGB color system.


The vase works as a three dimensional pixel were the RGB colors overlap to create a specific color which appears only once the vases are nested. Each vase is made using the values of red, green and blue that make up the specific purple color (P242). When the three vases are nested, the light passes through, and mixes the three colors so that the purple becomes evident.


A computer is used to calculate the exact amount of color that each vase must have in order to achieve the desired color.

The RGB vases will be exhibited as part of " Eyes on Spanish Design" an exhibition about emerging Spanish designers organised by the ICEX together with the DDI which will take place at 100% Design during the London Design Festival next September.

    really great!

  • Bodkin – please email Oscar and tell him that this doesn’t work.

  • anton

    wow..simple idea..
    nice..like it…

  • That’s dope-now if it could just appear white or clear when it’s in the nested state.

  • I like that purple: almost an amethyst. Glass insulators (very thick) used to be that colour in the olden days of the Canadian railways. Now that was really great.

  • FERRAN10


  • Subliminal!!!

  • absolutely brilliantly simple and beautiful, i love the form too

  • guerilla

    I don’t really see the need for the green cylinder if the main idea was creating the purple hue – the purple is a product of the blue and red vases.

    However, the colors look nice together, especially in the final picture.

  • SnowBallCity

    I like. But you can throw any kind of geometrical colored glass anything at me and I’ll bubble up with gleeful “ooooohh cooool” everywhere.

  • bodkin

    i don’t usually leave vases nested together, it makes it difficult to get the flowers in. and i’m always being ‘encouraged’ by my partner to make sure the vases are always filled. i like the colour purple though.

    and i’ve had another idea, maybe you could fill the vases with coloured liquid, stick the calender from the previous article in and voila! more colours and a calender at the same time.

    also could you tell us what is special about the specific colour purple p242?

  • Absolutely beautifull. Design and science can be a very good combination.

  • Well done Bodkin, you lived up to your reputation 100%.

    Jesus man, you really missed the point again.

    Here be haters.

  • Andrew

    bodking is obviously jealous again, and his idea of what is design is from last century. Move on or you thinking will be become soon extinguish.

  • Bodkin:

    Why are you trying to rationalise your desire to write totally negative and totally unnecessary comments for their own sake?

    Come on be honest, you’re just a hater trying to look like a (failed) critic.

    Nobody cares if you can’t put flowers in a vase.
    Nobody cares if you don’t normally stack them.

    There is no need to write these things, but you do. This doesn’t make you intelligent or insightful – it simply places you in the category of ‘hater’.
    Oscar was right in saying that you were simply jealous – and his refusal to sink to your level of commentary is an affirmation of your lack of intelligence. Thank God there are losers like me who enjoying arguing with numpties like you.

    Sorry, but I’m just gonna push your dumb ol’ big red ’stop talking nonsense’ button.

    ….and tell you to capitalise your ‘i’ in future correspondence.

  • bodkin

    my wife cares if you can’t put flowers in a vase and i care if calenders don’t tell you what day it is. is this really hate?

    if hate is not liking someone trying to present something that does not work then i embrace your description. otherwise you may need to consult a dictionary.

    i can’t wait to present my next architectural scheme to my clients on your basis of what makes a good design, i’m sure they’ll be most pleased when the roof leaks, the stairs don’t go up and the doors won’t open. at least it will look nice and we can all congratulate ourselves on how good the design was

  • No Bodkin,

    you can put flowers in this vase.
    But that’s not what’s intersting about this vase.

    Open your eyes for God’s sake.

  • …. and just to be a pain in the butt, I’d like to mention that the flat roof of Corbusier’s Villa Savoye leaked like buggery and drove the owners out.

    It is however an architectural masterpiece.


  • I always love when a specific aspect of an object is taken and introduced to other objects specific aspects to create something that is greater then each aspect alone. The purple color or (P242) is astonishingly beautiful.

  • Felix

    to come to bodkin's defence i think his are perfectly reasonable criticisms. it is up to the designer to communicate how the object is meant to be used, and since stackable vases are not a product we normally see it'd be nice if Oscar gave some instructions. is it meant to be unused most of the time and kept stacked as an art object? it's not clear

    i think this design is nice but has a problem you see quite frequently in designs that try and make the 'stored' version of a product look better: when you disassemble it the concept is lost. then you just have three coloured vases with little of the appeal of the 3 together.

    I'd also not buy it until I'd seen it under normal light. There's nothing here to indicate that the glass would look so impressive outside of a photographer's studio
