When it comes to my PC’s security, I blindly trust Kaspersky products not just because Kaspersky products have been performing really well in the test results but also because Kaspersky Internet Security or Antivirus has never let me down in the past 7 years.
About a week ago, I reinstalled Windows operating system on my desktop computer. After installing the OS, I downloaded and started installing Kaspersky Internet Security. When I was asked to enter the product key of Kaspersky, I searched my PC as well as the external drive but couldn’t find the file containing the Kaspersky product license key that I had saved about 8 months ago.
Like many other security software out there, Kaspersky products also don’t offer an easy way to backup product license keys to a safe location. We have to manually jot down the key in a safe location or keep the Quick Start Guide (comes when purchased Kaspersky in an offline store), which contains the product key, in a safe location.
Although users who have legally purchased Kaspersky products can contact Kaspersky and submit all required information regarding the product purchase to get the product key from the support team, your request might be turned down if you can’t submit all required information.
Those of you who have legally purchased Kaspersky Internet Security or Kaspersky Antivirus program can easily recover your Kaspersky product key by following the steps mentioned in this article. The only condition though is that this method works only if you have registered your Kaspersky product.
This method is applicable to all Kaspersky products including Kaspersky Internet Security, Antivirus, and other programs.
Recover Kaspersky activation code
Method 1 of 3
Step 1: Head over to My Kaspersky page and sign-in to your account. Again, you’ll be able to sign-in only if you have registered your Kaspersky product.
Step 2: Here, click on the Codes tab.
Step 3: As you can see in the below picture, the 20 character product key of your registered Kaspersky antivirus or internet security will appear here. The page also provides information about the activation and expiration date of your registered key.
And if you haven’t registered your product, please do so the next time when you purchase a Kaspersky product.
Method 2 of 3
Another way to recover Kaspersky key
You can contact Kaspersky support team to request the product key be providing purchase information. To do so, you first need to head over to My Kaspersky link provided in Method 1, sign up for My Kaspersky, and then submit a ticket with detailed information.
Method 3 of 3
Request Kaspersky support to re-send your order
If you had purchased the Kaspersky software from the official Kaspersky Store, then you can request to re-send your order. But before requesting, please search your inbox first for the mail containing the license key. Usually, when you purchase software from any online store, the activation code or product key will be sent to your email address.
Hope this helps!

Color for Data Visualization
- Introduction
- Converters
- Precalculated palettes
- Sequential palette forheatmaps
- Multihue HCL Palettes with bezier interpolation and lightnesscorrection
This package provides
- prebuilt color palettes appropriate for data representation,
- functions for defining color palettes for data representation,
- utilities for analysis of palettes as perceived by normal andcolorblind viewers.
Color palettes for data should ideally be perceptually linear in allperceptual color dimensions (hue, chroma or saturation, lightness orluminance). Ideally, palettes should aslo be color-blind safe (i.e. theyshould preserve an appropriate mapping of data to perceived color forcolorblind viewers). Palettes may also need to be black and whiteprinter-friendly, if there is a chance plots will be printed ingreyscale. Additional requirements for color scales can include thepresence or absence of discontinuities and corners, maximizingdiscrimination between levels, and respecting semantic relationshipsbetween colors.
This package relies on the perceptually flat colorspace HCL, whichrepresents color as preceived by people with normal vision. HCLfunctions from the
grDevices
and colorspace
packages. This packagealso relies on the dichromat
R package to simulate color perceptionunder the three most common forms of colorblindness.Installation
Install the

functionsHex RGB to HCL

?hex2hcl

7 category qualitative palette for nominal data
See
?unipalette
for details- designed for high contrast against a white background, with gooddistinction among colors
- colors distinguishable under two most common forms of colorblindness
- colors distinguishable in greyscale for b/w printing
- Good for bar charts, box plots, pies, etc.
- Line should be relatively thick
- Points should be relatively large
Sequential palette for heatmaps
A replacement for
grDevices::heat.colors()
or colorspace::heat_hcl()
See
?heat
for detailsPalette characteristics:
- perceptually linear
- color-blind-safe (under three most common forms of colorblindness)and print friendly
- under normal vision: linear lightness, chroma, and hue gradients
- under colorblind viewing, linear lightness, smooth chroma, flat huegradients
- appropriate for display of temperature, intensity, etc.
Comparison of Heat Palettes
Divergent colorscale for AUC heatmaps
See
?AUColors
for detailsPalette characteristics:
- color-blind-safe (under three most common forms of colorblindness)
- perceptually linear
- equal brightness gradients on both sides of central value
- constant hue and chroma on either side of central value
- Dark value for no correlation (near 0.5); bright values for highcorrelation (near 1 and 0)
- Blue for positive correlation (1); orange for negative correlation(0)
- NOT suitable for b/w printing, as low and high values are notdistinguishable in greyscale (however, greyscale printing stillaccurately shows the absolute distance from 0.5)

multihue()
, multihue.diverge()
and multihue.constantL()
createmulti-hue (multi “stop”) color scales with perceptually linear lightnessgradients and smooth hue gradients (with no first or second orderdiscontinuities).The palettes follow bezier curves through HCL space. The bezier curvesare defined by two endpoint colors and one or more optional intermediatecolor “stops.” The intermediate stops are treated as control points forthe bezier curve, and are therefore not necessarily present in the finalpalette.
After interpolation, the palettes are stretched to counter anynon-linearity in lightness gradient arising from the presence ofintermediate color stops. The resulting palette has a perceptuallylinear lightness gradient.
multihue.diverge()
builds a divergent palette by concatenating twobezier curves (defined by a “left” and “right” set of color stops).See
?multiHue
for description of multiHue()
, multiHue.diverge()
and multiHue.constantL()
For a discussion of bezier interpolation in HCL with lightnesscorrection, see:
Gregor Aisch. Mastering Multi-hued Color Scales with Chroma.js. Blogpost. Sep 9, 2013https://www.vis4.net/blog/2013/09/mastering-multi-hued-color-scales/
Palette characteristics:
- perceptually linear lightness gradients (or constant lightness for
multihue.constantL()
) - smooth hue and chroma gradient throughout (no “corners”)
- multiple color stops allow increased color discrimination betweenlevels
- hue and chroma gradients not necessarily linear. Only brightness isadjusted for linearity.
multihue()
,multihue.diverge()
produce print-friendly palettes.multihue.diverge()
may produce a palette with a centraldiscontinuity (first or second order)
Comparison with non-bezier multi-hue palettes
By comparison, here is the “rainbow” palette showing discontinuitiestypical of multi-hule palettes. This palette includes corners (secondorder discontinuities) in lightness. From a perceptual point of view,this palette is not a continuous colors scale, but a multiply-divergingscale with three distinct articulation points (at 1/6, 1/2 and 5/6 ofthe palette length).
