This question is impractical as the color is unrelated to the heat level. Red Jalapeños are fully ripened and sweeter. The main factors which affect heat are the type of jalapeno plant, temperature at time of bloom pollination, sun exposure, watering frequency and amount of fertilizer provided.
For example, a jalapeño who's bloom was pollinated at 85f, kept in full sun, stressed by only watering when it wilted, and withheld nitrogen may be a scorchingly hot pepper either green or red. Similarly, if the variables were reversed, you may have a mild pepper regardless of color...
Red chilies are generally hotter than green chilies. Red chilies have the most capsaicin, so they are more intense and longer lasting than green chilies. The red and green chili peppers have one thing in common: they're both popular peppers around the world.
"Hotness" comes from the capsaicin in the pepper. Some, like green bell peppers, have none. Jalapenos have some. Sorrenos, more. Habaneros, a LOT more. The more capsaicin, the hotter the pepper. Now go look up Scoville Heat Units- that is the scale used to compare hotness. PS, hotter is not always better.
As jalapenos and other green chiles ripen on the plant, they usually gradually change from green to red. Red ripe jalapenos have a slightly different flavor than green ones, but most people find them even better because they get a more complex flavor. You don't see many red jalapenos at regular super markets because they are usually shipped very green to make them have a longer shelf life and bruise less during shipping. The flesh of very ripe jalapenos can be a little thinner than green ones, so they may not be as good for stuffing as green ones are. They can substute for each other in most recipes. If you have heard of chipotle chiles (pronounced "chip-OAT-lay", they are ripe red jalapenos that have been dried and smoked and then often canned in adobo sauce, but you can also find them in their dried state without sauces.
The main difference between serrano and jalapeno peppers is their level of spiciness. Serrano peppers are hotter than jalapenos, with serranos typically ranging from 10,000 to 23,000 Scoville heat units, while jalapenos range from 2,500 to 8,000 Scoville heat units.
If you have more jalapenos than you need straight away you can preserve them in a jar of extra virgin olive oil and use them as and when needed.
Its colour. White stars are hotter than blue stars which are hotter than yellow which are hotter than orange, which are hotter than red.
Green flames are typically not as hot as blue flames, but are hotter than red or orange flames.
A green flame is typically not as hot as blue or white flames, but hotter than red or orange flames.
Cayenne peppers are generally spicier than jalapenos.
Because orange is hotter than yellow
