How Colorblind People See Food & Fruit
Color is one of our primary tools for judging food quality, ripeness, and safety. For people with color blindness, many of these visual cues are diminished or absent. This simulation shows how common foods appear through colorblind eyes, including important safety scenarios like determining whether meat is properly cooked.

Color and Food Safety
Color is one of the most important visual indicators of food safety, and color blindness can compromise this assessment. The most critical example is judging whether meat is properly cooked — the transition from raw pink to cooked brown relies on exactly the red-green color distinction that is impaired in the most common types of color blindness. Ground beef, in particular, can be difficult to assess because the interior color change from pink to brown is subtle even for people with normal vision. Colorblind cooks should rely on a meat thermometer rather than visual appearance, which is actually the recommendation for all cooks regardless of color vision.
Judging Fruit Ripeness
Many fruits signal their ripeness through color changes that are challenging for colorblind people to detect. Bananas transitioning from green to yellow are reasonably visible to most people with red-green deficiency since the brightness change is significant. However, the green-to-red transition of tomatoes, strawberries, and apples is much harder to assess. A tomato that appears obviously red to someone with normal vision may look like a slightly different shade of olive-brown to someone with protanopia. Colorblind people often develop alternative strategies — squeezing for softness, smelling for ripeness, or asking others for visual confirmation.
Cooking and Meal Preparation
In the kitchen, color blindness creates a range of practical challenges beyond food safety. Browning onions or garlic requires watching for color change from white to golden to brown. Judging when a sauce has reduced properly, when bread is toasted to the right shade, or when vegetables have been roasted to the desired color are all tasks that rely on red-green-brown discrimination. Some colorblind cooks report overcooking food as a safety precaution — ensuring meat is well done rather than risking undercooking. Timing-based cooking (using timers and temperature probes) is generally more reliable than visual assessment for colorblind cooks.
Shopping for Produce
Selecting fresh produce at the grocery store or farmers market can be frustrating for colorblind shoppers. Distinguishing ripe red apples from green ones, finding perfectly ripe avocados, and selecting tomatoes at the right stage of ripeness all depend on color discrimination. Colorblind shoppers may unknowingly select underripe or overripe produce, leading to food waste. Some adaptations include shopping at stores with labeled ripeness information, using smartphone apps that can identify colors, or developing a preference for produce where ripeness is indicated by texture rather than color (like avocados, which darken and soften when ripe).
Food Presentation and Social Dining
Color plays a significant role in how appetizing food appears. The culinary principle that people eat with their eyes first means that colorblind individuals may not experience the same visual appeal from beautifully plated dishes. A garnish of red peppers on a green salad, for instance, may lack the visual contrast that makes it appealing to others. In social dining situations, colorblind people may occasionally encounter confusion when asked to identify foods by color — for example, distinguishing between similar-looking salsas, identifying cranberry sauce versus gravy, or navigating a colorful buffet. Most people develop effective coping strategies and find these situations more amusing than distressing.
Frequently Asked Questions
Is it dangerous for colorblind people to cook meat?
It is not inherently dangerous, but colorblind cooks should take extra precautions. The visual transition from raw pink to cooked brown is one of the most common color changes that people with red-green color blindness have difficulty detecting. The safest approach is to use a meat thermometer to check internal temperature: 165F (74C) for poultry, 160F (71C) for ground meats, and 145F (63C) for whole cuts of beef, pork, and lamb. This is actually the recommended practice for all cooks regardless of color vision, as visual assessment alone is not always reliable.
Can colorblind people tell if food has gone bad?
Color changes associated with spoilage can be harder for colorblind people to detect — for example, green mold on bread or the gray-green discoloration of expired meat. However, color is only one indicator of spoilage. Smell is often a more reliable indicator, and most spoiled food develops obvious off-odors before color changes become apparent. Texture changes (sliminess, unexpected softness), taste, and expiration dates are all non-color-dependent indicators. Colorblind people should pay extra attention to these alternative cues and err on the side of caution when uncertain about freshness.
Do colorblind people taste food differently because it looks different?
Research suggests that visual appearance does influence taste perception and appetite. Studies have shown that food color can affect expectations and perceived flavor intensity. However, the degree to which this affects colorblind individuals in practice is probably small, since they have adapted to their visual experience throughout their lives. A colorblind person has no reference point for what 'normally colored' food looks like, so their baseline expectations are already calibrated to their own visual experience. The taste, smell, and texture of food remain identical regardless of color vision status.

Protanopia Simulation: See What Red-Blind People See
Protanopia is a type of red-green color blindness where the long-wavelength (red) cones in the retina are completely absent. People with protanopia cannot distinguish between red and green, and red colors appear much darker than they do to people with normal vision. This simulation shows how common colors look to someone with protanopia.
Deuteranopia Simulation: Green-Blind Vision
Deuteranopia is the most common form of color blindness, caused by the absence of medium-wavelength (green) cone photoreceptors. Like protanopia, it is a type of red-green color blindness, but the affected colors shift differently. People with deuteranopia have difficulty distinguishing between reds, greens, browns, and oranges. This simulation demonstrates how everyday colors appear through deuteranopic vision.
How Colorblind People See Nature & Sunsets
Nature's vibrant palette of greens, reds, oranges, and blues can look dramatically different through colorblind eyes. For people with red-green color blindness — the most common type — lush forests, colorful sunsets, and autumn foliage lose much of their contrast and variety. This simulation compares how natural colors appear to people with protanopia and deuteranopia, the two most common forms of color vision deficiency.
