In a rainbow or the separation of colors by a prism we see the continuous range of spectral colors (the visible spectrum). A spectral color is composed of a single wavelength and can be correlated with wavelength as shown in the chart below (a general guide and not a precise statement about color).
How Much Do Mold Inspections Cost? Mold inspection costs vary widely depending on the size of the property, extent of the mold inspection, number of mold samples, and other factors. We've heard of price quotes as low as $300 and as high as $3,000. While cost is clearly an important factor for most people, we recommend including other factors besides the mold inspection cost when choosing a mold inspector.
1 Most mold test kits that can be purchased over the counter are going to cost anywhere from $10 to as much as $125. 2  These prices are for the kits themselves, however, and will not include the professional lab testing.3  For instance, the IAQ Pro 5-Minute test can retail for $39.99 for the kit alone. A professional mold test is going to cost anywhere from $250 to as much as $700 depending on the amount of mold that needs to be tested.
