{"product_id":"9783721205725","title":"Colorondo, a Game with 80 Colors","description":"If you release a chip from one of the five coloured boards and place it on a different-coloured background, its color suddenly appears different to the one it had in its previous environment. Why is that? Colorondo provides a hands-on experience of the phenomenon of simultaneous contrast heightening. Pages of instructions are quite superfluous, as you don t need theory to observe the amazingly versatile interaction of colours. All you need is a keen eye and a willingness to try out different variations. There are 79 possible combinations for each of the 80 colours.","brand":"Niggli","offers":[{"title":"Default Title","offer_id":47060518895856,"sku":"9783721205725","price":39.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9783721205725_p0.jpg?v=1763670037","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9783721205725","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
