It’s not possible, no matter how much code they right to figure it out. This is no different then taking a picture of a color sample from Moore buy appstore reviews, and being surprised that it doesn’t match. It’s because the light is colored, various intensity, and…. cheap camera. I can say with great certainty, that there is no color neutral light source you are likely to come across at any point in your day. The sun, incandescent light bulbs, fluorescents, LED’s… all have a color tint to them. That “”pure white”” bulb you bought at Lowe’s for $10 is not pure white.
You’re not going to find neutral white bulbs unless you’re at a special studio where they’ve spent a lot of money on them. And even then you would still need to calibrate your camera to the bulbs. Not to mention, the phone’s screen will not be a 100% accurate match. Because while every screen may seem similar… they’re not perfectly matched either.
Second. “”The only color that comes up is Kentucky Haze””. Yes, that is the default color that comes up. Easy misunderstanding. When you load a photo, and you may have zoomed into the color you want (you don’t have to by the way) the selector defaults to “”kentucky haze””. That’s because you still need to touch the screen to sample the color. The sample happens under your finger, but pops up a bubble above your finger to show you what you’re selecting.
Also, please keep in mind that digital images have mini-variations from pixel to pixel as you move across an image. So if you sample a red flower, but get brown in one spot, yellow in another, and mostly a red-ish. It’s due to the digital ‘noise’ in the photo. Something that can help with this is to use a free photo app to blur the image before selecting. This averages out the noise to give a solid color. Or, just be patient and keep selecting around the area you like until you get a color that you think feels right.
Third, search by number. Actually you can do this. Select “”Color Wheel”” on the bottom. Then, if you see the color wheel, select the Magnifying glass ‘search’ icon in the upper left. This will change the screen to a text field to enter the name or number of the color you’re looking for.
As for some of the other buy mobile app installs criticisms, they have they’re own merit. I didn’t feel that the interface was clunky at all. It felt vary intuitive to me. Others didn’t, and that’s very possible. I’ve only just started using the app, so I haven’t lost any selections from an update. So I can’t speak to that point either. However, I know that the moment my wife pickets out a color for a project she has several swatches in the project folder to physically put on the wall in the room, under proper lighting conditions for that room.
