    <p><strong>The problem:</strong> I want to mix two colors in javascript, and get the result color. There are a lot of similar question on SO, however I doesn't find anything that actually works correctly. I know that mixing two different colored paints(pigments) and lights will give very different results (<a href="http://en.wikipedia.org/wiki/Color_mixing" rel="noreferrer">http://en.wikipedia.org/wiki/Color_mixing</a>). </p> <p>Here are the questions and suggested solutions I've already seen, and tried to implement:</p> <p><strong>1:</strong> <a href="https://stackoverflow.com/q/1892020/240324">Mixing two RGB color vectors to get resultant</a> <br/> So, mixing colors in RGB. I implemented it, and in some cases it works in some cases it doesn't.</p> <p><strong>Working example:</strong> Mixing <code>red</code> with <code>yellow</code> -> <code>orange</code>. Great!<br/> <a href="http://jsbin.com/afomim/1/edit" rel="noreferrer">http://jsbin.com/afomim/1/edit</a></p> <p><strong>Not working example:</strong> Mixing <code>blue</code> with <code>yellow</code> -> <code>gray</code>. Not so great! :) <a href="http://jsbin.com/afomim/5/edit" rel="noreferrer">http://jsbin.com/afomim/5/edit</a><br/> I know that in RGB mixing <code>blue</code> with <code>yellow</code> will never make <code>green</code>, and I understand why. </p> <p>We will not find the answer here, let's go forward.</p> <p><strong>2:</strong> <a href="https://stackoverflow.com/q/10139833/240324">Adding Colours (Colors) Together like Paint (Blue + Yellow = Green, etc) </a></p> <p>Let's try to work with CMYK values as suggested in this discussion. Mixing <code>cyan</code> with <code>yellow</code> gives <code>green</code>: <br /> <a href="http://jsbin.com/igaveg/1/edit" rel="noreferrer">http://jsbin.com/igaveg/1/edit</a> <br /> but mixing <code>blue</code> with <code>yellow</code> results in <code>black</code>. <br/> <a href="http://jsbin.com/igaveg/2/edit" rel="noreferrer">http://jsbin.com/igaveg/2/edit</a> -> Not working!</p> <p><strong>3:</strong> <a href="https://stackoverflow.com/q/398224/240324">How to mix colors &quot;naturally&quot; with C#?</a><br/> A very similar question. The most upvoted answer suggests to convert colors to LAB, and this solution seems promising.<br/> So I converted my colors to LAB. The conversion algo is correct, I tested it!</p> <p><a href="http://jsbin.com/oxefox/1/edit" rel="noreferrer">http://jsbin.com/oxefox/1/edit</a></p> <p>Now I have the two colors in LAB, but how to mix them?</p> <p><strong>NOTE</strong> I know that probably I will not find an algo that mixes <code>blue</code> with <code>yellow</code> and will give the perfect <code>green</code>, but I hope I can generate something similar to green :)</p>

    1. COI am just curious: Why should blue and yellow mix to green (or something similar)?

    2. COBy blue I doesn't meen exactly #0000ff, and or by yellow #ffff00, but in real world, if you mix some blue with some yellow, most of the time you got some green. This app: http://www.fiftythree.com/paper (awarded by apple) has some great color mixing functions, and they say they were working on it more than a year :) If you check their page, you see that they apply the same theory about blue and yellow.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
