Pure calcite crystal it transparent, but generally defects make it a slightly translucent white color. Powdered calcite is white.
Solar glow thread is a type of fiber that is designed to glow in the dark after being charged by exposure to sunlight or other light sources. It is often used in textiles, crafts, and outdoor gear to enhance visibility in low-light conditions. The thread contains phosphorescent materials that absorb light and then emit it slowly over time, making it useful for safety applications and decorative purposes. Its unique properties make it popular among crafters and manufacturers looking to add a luminous effect to their products.
You can make dark blue in a very easy way. You just need to add a darker color like purple, black, maroon to blue to get dark blue.

Light can pass through some materials. An example of a material like this would be glass. It cant go through all materials. When materials let light through, we call that transparency.
It depends on the luminescence of the materials. I see no difference between "the light source" and "the intensity of the light". Please restate and/or clarify the question.
Because it's dark that's why the shadow is dark.no it is because there is nothing there! so it becomes black or shadowed color
Glow-in-the-dark silicone bracelets are made with phosphorescent materials that absorb and store light energy when exposed to light. When in the dark, they slowly release this stored light energy in the form of a dim glow. The process is called phosphorescence.
Materials for making glowing water include a fluorescent or phosphorescent substance, such as a fluorescent dye or glow-in-the-dark powder, water, and a black light or UV light source to make it glow. These materials can be combined in varying quantities to achieve the desired glowing effect.
both.
Probably not. At one time a radium compound was used to make watches that glowed in the dark. This is no longer done, and most glow in the dark materials are now simply phosphorescent. The kind that need to be "charged up" by exposure to light and go dark after a few minutes to an hour or so are not radioactive.
Burn it
Yes, you can
Light purple.
Luminous means "giving off light", or glows in the dark (since luminosity is detected by the eyes, it usually refers to the visible part of the electromagnetic spectrum). Many materials emit a wide range of radiation other than visible light, which is why some radioactive materials were used as glow in the dark paints, and why the Curies focused on a particular radioactive isotope (because it glowed in the dark). Some materials can even store energy from visible light and emit it later, which is why some of my luminous objects have to be "charged" by a light bulb or the sun. Some chemical combinations can emit light for a while, such as the stuff in lightning bugs, which we can replicate in production lines to make glow sticks. Non luminous materials do not emit light that we can see. Most elements that are not radioactive fall into this category.
Dark. There is no light. It has no plant life because there is no light to make it grow, even though it is in the water.
