Red and yellow
An object appears a certain color because it reflects specific wavelengths in the visible spectrum while absorbing others. For example, a blue object reflects blue wavelengths and absorbs other colors.
The reddish-yellow color of the leaves indicates that the pigment is absorbing blue and green wavelengths of visible light. This is because pigments appear as the complementary color to the wavelengths they absorb - in this case, absorbing blue and green results in the reddish-yellow color we observe.
The visible spectrum wavelengths of Krypton fall in the range of approximately 440 to 740 nanometers. This corresponds to the blue to red part of the visible light spectrum.

The spectrum of helium consists of distinct lines at specific wavelengths, known as emission lines, due to the transition of electrons between energy levels. In contrast, the spectrum of white light from the Sun is continuous, with all visible wavelengths present. The presence of absorption lines in the solar spectrum, caused by elements in the Sun's atmosphere absorbing specific wavelengths, further distinguishes it from the discrete emission lines of helium.

Refer to the EM spectrum to find exact answer about this question. Usually wavelengths are listed at bottom and frequency on top of the spectrum. Gamma rays have the smallest wavelength.
The visible spectrum of the electromagnetic spectrum of radiation
Visible light falls between the wavelengths of 380 nm and 760 nm in the electromagnetic spectrum.

The longest visible wavelengths are thoseat the red end of the spectrum (rainbow).
The human eye can only detect electromagnetic radiation in the visible spectrum, Typically, wavelengths of 390 to 750 nm fall within the visible spectrum. Radiation with these wavelengths are called visible light or simply light.
The spectrum that encompasses all wavelengths of light is known as the electromagnetic spectrum. It includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays, ranging from longer wavelengths with lower frequencies to shorter wavelengths with higher frequencies.
Wavelengths in the range of 0.4 - 0.7 microns are visible.
